Visionstar TR-700

Product Code: EOAS-OD-2955

Three arms and the power supply. No chair, and that is the point.

The column on its own. The TR-700 carries a phoropter arm, a projection arm and a slit lamp arm with the full instrument supply — and leaves the seating to whatever a practice already has.

The Visionstar TR-700 is the column and arm assembly from its stablemate, supplied without the chair. Three arms are specified rather than four: a phoropter swing arm rated 30 kg with 900–1500 mm travel, a projection arm rated 10 kg with 360° rotation and 1030–1530 mm travel, and a slit lamp arm rated 50 kg whose table moves within a semicircle of 824 mm radius across 716–1016 mm of height. The auto keratometer arm published on the fuller model is absent here, as are all seat parameters.

That makes this a different purchase rather than a lesser one. A practice replacing an ageing instrument column frequently has seating with years of service left in it, and buying a complete unit means paying for a chair to replace a chair that works. Supplying the column alone lets the expensive, technically complex part be renewed while the simple, durable part stays where it is.

The electrical specification is unchanged from the full model, and it is what makes the column worth buying on its own. Alongside mains passthrough at 100–120V and 200–240V AC, the unit supplies switched low-voltage AC at 2.5, 3.5, 4.5, 5.5, 6.5, 7.5 and 12 volts, with 5V DC charging. Engine power is 28V 1.5A DC and lighting 5/16W 24V DC, on a 5 A 130/250 V fuse and 10 A 120/250 V main wire, with 1 W no-load draw, a 2 kV pressure test, S1 continuous duty and a −10 °C to +40 °C envelope.

So a practice adding this column gains the instrument supply as well as the arms — the ability to run instruments from taps rather than from a bank of individual adaptors, which is a retrofit benefit as much as a new-installation one.

Two things need establishing. The published 1348 × 1274 × 1556 mm envelope explicitly excludes the table top and lighting, so the installed footprint is larger than stated. And no weight is published at all, where the fuller model states 295 kg — an omission that matters for floor loading and for planning delivery.

Column replacement without chair replacement is the application, and it addresses a mismatch practices meet regularly. Instrument columns and examination chairs wear out on different timescales: the column carries mechanisms, electronics and mounting geometry that date, while a chair is upholstery over a lift and lasts considerably longer. Buying a complete unit to replace an ageing column means paying to replace a chair that works, and disposing of it.

Practices upgrading instrument mounting benefit most directly. Three arms rated 30, 10 and 50 kg cover phoropter, projection and slit lamp, with per-arm figures published so an instrument can be matched to a mount before ordering.

Instrument power is the less obvious gain. The full multi-tap supply carries over unchanged — 2.5 through 12 volts AC plus 5V DC charging — so a practice retrofitting this column also retires the bank of individual adaptors behind its instruments. That is a benefit older premises feel more sharply, since mains outlets are usually scarcer there.

Rooms with recently purchased seating suit it obviously. So do practices that chose their chair deliberately for accessibility reasons and do not want it changed.

Three things need establishing. The published envelope of 1348 × 1274 × 1556 mm excludes the table top and lighting, so the installed footprint is larger. No weight is published at all, where the fuller model states 295 kg — request it for floor loading and delivery. And the geometry between this column and a specific existing chair should be checked rather than assumed: the arms cover 716 to 1530 mm across their travels, which is generous, but chair height and position both matter.

Renew the column, keep the chair

Columns and chairs wear out on different timescales. Buying a complete unit means paying to replace seating that works, and disposing of it.

The instrument supply comes with it

Switched AC taps from 2.5 to 12 volts plus 5V DC charging carry over unchanged, so a retrofit upgrades instrument power as well as instrument mounting.

Retires the adaptors behind the instruments

Older premises have fewer mains outlets and more power bricks. Running instruments from taps addresses both, and it arrives as part of the column.

Three arms with published load ratings

Thirty, 10 and 50 kilograms across phoropter, projection and slit lamp arms — enough granularity to match an instrument to a mount before ordering.

A slit lamp arm rated for the job

Fifty kilograms with table movement inside an 824 mm radius semicircle and 716–1016 mm of height, for the heaviest instrument in the room.

Suits a chair chosen deliberately

Practices that selected their seating for accessibility reasons keep it, rather than accepting whatever a complete unit supplies.

Full electrical schedule published

Input, output taps, engine power, lighting, fuse and wire ratings, duty classification and operating envelope — enough for an electrician to specify a circuit before attending.

Phoropter swing arm

Swing ±30°, rotary arm 0–300°, travel 900–1500 mm, maximum load 30 kg.

Projection arm

Rotary arm 360°, tray 360°, travel 1030–1530 mm, maximum load 10 kg.

Slit lamp arm

Table 350 × 200 × 25 mm, customisable to a maximum 700 × 400 × 40 mm; movement within a semicircle of 824 mm radius; height 716–1016 mm; rotary arms at 0–180°, 0–360° and 0–180°; table board 360°; maximum load 50 kg.

Seven switched AC outputs

Output at 2.5, 3.5, 4.5, 5.5, 6.5, 7.5 and 12 volts AC, alongside mains passthrough at 100–120V and 200–240V.

5V DC charging output

A dedicated charging supply is provided; available current is not stated.

No seating supplied

The datasheet publishes no seat parameters, unlike the fuller model in this family — this is the column and arm assembly alone.

1348 × 1274 × 1556 mm

The published envelope excludes the table top and lighting; the installed footprint is larger.

Full electrical schedule

Engine power 28V 1.5A DC, light 5/16W 24V DC, 5 A 130/250 V fuse, 10 A 120/250 V main wire, 1 W no-load draw, 2 kV pressure test, S1 continuous duty, −10 °C to +40 °C.

The Visionstar TR-700 is the column and arm assembly from its stablemate, supplied without seating: three arms rather than four, and no seat parameters at all. That is a different purchase rather than a lesser one, because instrument columns and examination chairs wear out on different timescales — the column carries the mechanisms and mounting geometry that date, while a chair is upholstery over a lift and lasts considerably longer. A practice replacing an ageing column with a complete unit is paying to replace a chair that works, and disposing of it. Buying the column alone renews the technically complex part and leaves the durable part in place. The full instrument supply carries over unchanged, so a retrofit gains switched AC taps from 2.5 to 12 volts plus 5V DC charging as well as new arms — retiring the bank of adaptors behind the instruments, which older premises feel more sharply. Three things to establish: the published envelope excludes the table top and lighting, no weight is published at all where the fuller model states 295 kg, and the geometry between this column and a specific existing chair should be checked rather than assumed.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

No. The datasheet publishes three arms and the full electrical specification, and gives no seat parameters at all — where the fuller model in this family publishes lift, headrest, rotation, footrest, backrest and load figures. This is the column and arm assembly on its own.

Because seating and instrument columns wear out on different timescales. A practice replacing an ageing column frequently has a chair with years of service left, and a complete unit means paying to replace something that works. Buying the column alone renews the technically complex part and leaves the durable part in place.

A phoropter swing arm rated 30 kg with 900–1500 mm travel, a projection arm rated 10 kg with 360° rotation and 1030–1530 mm travel, and a slit lamp arm rated 50 kg with table movement within an 824 mm radius semicircle across 716–1016 mm of height.

The auto keratometer arm and all seat parameters. Everything else — the other three arms and the entire electrical schedule — is identical.

Yes, and unchanged. Switched AC outputs at 2.5, 3.5, 4.5, 5.5, 6.5, 7.5 and 12 volts plus 5V DC charging, alongside mains passthrough. That makes it a retrofit that upgrades instrument power as well as instrument mounting.

That needs checking case by case. Voltage alone does not establish compatibility — current capacity, connector type and whether an instrument expects AC or DC all matter. Provide your instrument list at enquiry and have it confirmed in writing.

That depends on the chair's height range and its position relative to the column. The arms cover 716–1530 mm across their travels, which is generous, but geometry between a specific chair and this column should be checked rather than assumed. Send chair dimensions at enquiry.

1348 × 1274 × 1556 mm, stated without the table top or lighting fitted. The installed envelope is therefore larger and should be established before planning a room.

Not published, unlike the fuller model which states 295 kg. Since this omits a chair and one arm it will be lighter, but by how much is unstated. Request the figure for floor loading and delivery planning.

The electrical side is fully specified; the physical side is not. Confirm floor loading, delivery access and positioning labour, and allow clearance for three arms to swing plus whatever your existing chair requires.

An ophthalmic examination unit is generally classified as Class I under the UK Medical Devices Regulations 2002, or higher where configuration dictates. Manufacturer CE marking is noted where it appears in the product literature; Medigear.uk confirms CE marking, the declaration of conformity and current UKCA status against the shipping batch at quotation rather than asserting it in advance.

Periodic inspection of all three arms for developing play, fuse replacement to the stated 5 A 130/250 V rating, and cleaning of surfaces with an approved agent. Establish the output supply's service requirement separately, and confirm what happens to instrument power if it fails — that component has no equivalent in most units this column would be replacing. Typical warranty is 12 to 24 months against manufacturing defect, confirmed at quotation.
