GB/T479-2016 "Determination Method for Index of Colloidal Layer of Bituminous Coal"
1. Self diagnose 7 common faults, which can control the heating speed of both the front and rear furnaces simultaneously, or separately control the heating speed of the front and rear furnaces.
2. If the instrument is powered off for a short period of time and restarted, it can restore its working state before the power outage to prevent the sample from being scrapped. The controller has two types: digital display and LCD display.
3. Comply with the requirements of the national standard GB/T479-2000 "Determination Method for Index of Bituminous Coal Colloidal Layer".
4. Flexible and convenient operation, stable and reliable performance.
The gelatinous layer analyzer is a specialized instrument used for measuring the gelatinous layer index of bituminous coal, including three indicators: the thickness Y of the gelatinous layer, the final shrinkage X, and the type of volume curve.
