Packing List

1. ATAGO portable digital refractometer 1 set
2. Fixture set 1 set
3. Two spare rubber flat probes
4. Two spare rubber round measuring heads
5. Three pairs of silicone tweezers
6. Four spare batteries
7. One refractometer storage box

Suggested operating steps:

1. Place a pure water droplet on the prism in the test slot, measure with 【 START 】, and then calibrate the refractometer to zero with 【 ZERO 】.
2. Remove excess moisture from the surface of the balanced contact lens and stick the concave surface onto the rubber probe (with the convex surface facing outward).
3. Press down the pressure arm of the fixture until the lock is locked.
4. Press the 【 START 】 button to start measuring, and after a few seconds, read the measurement data from the LCD screen.
Repeat more than three times and calculate the average.
