The gloss meter calibration standard refers to black glass with a refractive index of 1.567. Assuming that the glass is in a state of ideal polishing, the gloss of the black glass is defined as 100 GU at this time, so the gloss meter is a relative measurement instrument, so a standard board is required for each test to determine the relative measured glossiness.
As an international measuring instrument, the gloss meter has a uniform gloss meter calibration standard. As shown in the figure below, the gloss meter is divided into a first-level machine and a second-level machine. For general use requirements, the second-level gloss meter can meet the demand. However, if the requirements are relatively high, it is necessary to consider the first-level gloss meter.
The preservation and use of the glossmeter calibration standard board can affect the accuracy of the data. If the standard board is worn, the contamination will affect the calibration standard of the gloss meter. Linshang gloss meter calibration standard board is located on the bottom cover of the instrument. Each time it is used, the instrument needs to be placed back on the bottom cover. This operation can keep the light hole at the bottom and the gloss meter calibration standard board on the bottom cover clean.
In addition, the gloss meter is also recommended to be calibrated once a year. If it is used frequently, we also recommend that the customer return it to the factory for calibration once every six months, or replace the gloss meter calibration standard board.
Linshang Technology has provided calibration and maintenance service to the gloss meter and calibration standard boards. For more product information, please refer to “LS191 gloss meter”.
