Lightweight, cordless models can be carried any place.

 

No cord to obstruct handling the lens meter.

  FEATURES

New refined appearance with convenience-oriented design ensures operational ease.

Troublesome lamp replacement is eliminated by an LED light source.

The auto power-off function maximizes battery life even when the OFF-switch is forgotten.      The batteries run for more than 200 hours continuously, and the power-off time is adjustable      ( 2-6 min. ).

Can be clamped at any angle within from 45° ~ 90° allowing measurement while in a      comfortable position.

Can be tilted to a full 90° for easy measurement of contact lenses.

When an AC adapter is connected, the battery supply circuit is automatically closed to save      battery life..
