1．Simple operation

The test can be started after turning on the test. The test does not require any keys. The instrument can measure the gloss value on the surface of the material.

2．High precision

The LS191 gloss meter has high accuracy, which can ensure that it can pass the testing of any Chinese authoritative metrology institute and meet the standards of national first-class working machines. There is no big difference with the test data of imported gloss meter.

Stable value 0.2GU 0.4GU 1.0GU

Zero value error 0.1GU 0.2GU 1.0GU

Indication error ±1.0GU ±1.5GU ±2.5GU

3．Smart statistics

As a result of multiple consecutive tests, the LS191 gloss meter can automatically calculate the maximum, minimum, average and mean square error values. After a multi-point test of the material, this function can be used to analyze the uniformity of the tested material gloss.
