Standard Gas/Calibration Gases
It mainly includes: gas for environmental departments, automobile exhaust gas, gas for petrochemical industry, gas for electronic industry, gas for petroleum exploration logging instrument, gas for toxic and harmful detection, gas for combustible gas alarm instrument
Description
Reference gases belong to reference materials. Reference materials are highly uniform and accurate measurement standards, which have the basic function of reproducing, preserving and transmitting quantitative values.
Application
Standard gas can also be used for environmental monitoring, toxic organic matter measurement, automobile emission gas testing, natural gas BTU measurement, liquefied petroleum gas calibration standards, supercritical fluid process, etc.
In the field of physical, chemical, biological and engineering measurement, it is used to calibrate measuring instruments and measuring processes, evaluate the accuracy of measuring methods and testing laboratory testing capabilities, determine the characteristic value
Large vinyl plants, ammonia plants and other petrochemical enterprises, in the device start, stop and normal production process need dozens of pure gas and hundreds of multi-component standard mixture, used to calibrate, calibrate the production process used in the online analysis instruments and analysis of raw materials and product quality instruments.
