- 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.
