IV. LS191 Gloss Meter Features
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.
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.
|Measuringinstrument||StandardGloss meter||First working-classGloss meter||Secondary working-classGloss meter|
|Zero value error||0.1GU||0.2GU||1.0GU|
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.
4．Power on self test
The instrument has the function of automatically checking the standard version when it is turned on. It can automatically judge whether the standard plate is contaminated and give a prompt to avoid inaccurate measurement caused by the standard plate contamination affecting the standard value.
5．PC software operation
The LS191 gloss meter is shipped with PC software from the factory. It can be connected to a computer via a USB cable to enable automatic computer measurement. And test data can be archived to generate test reports.
6．Stable test data
There is a white LED light source in the gloss meter. The luminous efficiency of the light source will change with the change of temperature, so the ordinary gloss meter needs to be calibrated before the test. The Linshang gloss meter has temperature compensation function. When the temperature difference changes very much, it does not need to be calibrated every time it is turned on. And this gloss checker can ensure the stability of the test data. Especially in northern China, the temperature difference between morning and evening is very prominent.
The LS191 gloss tester has small size. It is designed with all-aluminum material. It is very convenient to carry out and not afraid of various crash that may affect the appearance.
8．Ultra-low power consumption
This gloss tester is powered by a built-in lithium battery, which is energy-saving and environmentally friendly. It has ultra-low power consumption. The continuous uninterrupted test time can reach more than 50 hours.

VIII. FAQ about LS191 Gloss Meter
1. The difference between LS191 and LS192 gloss meters
The main difference between LS191 and LS192 is the gloss measurement range. The measurement range of LS191 gloss meter is 0-200GU, while the measurement range of LS192 is 0-1000GU. If you need to measure high gloss materials such as metal or mirror, you need to use LS192 gloss meter.
2. What is repeatability and reproducibility?
Repeatability is the difference between multiple measurements of the same sample under the same conditions, the same people, the same gloss meter and the same environment.
Reproducibility refers to the difference of measuring the same sample under different conditions, such as the same people using different gloss meters, or different people using the same gloss meter.
3. What is the zero value error？
When testing a material with 0 GU, the difference between the measured value and 0.
