ZRJ-2000 Coal Spontaneous Combustion Tendency Tester

ZRJ-2000 Coal Spontaneous Combustion Tendency TesterBy using chromatographic oxygen absorption method, the spontaneous combustion tendency index of coal samples was determined. The automatic injection processing system increased the original four-way processing to 8-way injection, improving the automation level. Automatic injection of 4-8 channels
Introduction to Computer Processing: Able to achieve 8-channel sampling and computer processing of data. It adopts the principle of chromatographic oxygen absorption.
Suitable for: laboratories, university research institutions.
