Introduction
XRY 1C type oxygen bomb calorimeter is based on the People’s Republic of China national standard GB/T 213 “Coal calorific value determination method”, GB/T 384 “Petroleum product calorific value determination Method”, the People’s Republic of China national metrology verification regulation JJG672 “Oxygen bomb calorimeter” and Shanghai enterprise standard Q/VCZK 10 “XRY Designed and manufactured according to the requirements of series oxygen bomb calorimeter.
This instrument is an automatic and intelligent instrument controlled by computer, which can automatically complete the calorific value test of combustible substances. It is an upgraded product of this type of instrument. Can be widely used to measure the calorific value of coal, oil, coke, paraffin and other combustible substances, is thermoelectric, coal, metallurgy, building materials, chemical, food and other industries, is the ideal choice for all related industries and departments.
Main technical features
1, the use of semiconductor refrigeration, the cooling capacity can be determined according to the heat level, the instrument automatically adjusts the water temperature, so that the water temperature remains relatively constant, continuous long time test to ensure accurate results.
2, the use of advanced USB interface, plug and play, a computer can control multiple calorimeters.
3, with electronic measuring cup, no need to manually weigh the water weight, automatic measurement of the inner cylinder water, repeated error < 0.4g.
4, can automatically measure the ignition wire resistance, automatically check whether the ignition wire is installed before the test.
5, standardized pipeline design, greatly shorten the pipeline, the pipeline is more reasonable, the experimental results are more accurate.
6, the use of special discharge water interface, instrument drainage, water change is more convenient and fast.
7, with the function of communication with electronic balance (optional), can realize the Internet remote data sharing
