Industrial process control is mainly used in coal chemical, metallurgical and natural gas, petroleum and petrochemical industries. In the production process, pure gas and standard gas are needed to calibrate the instrument to ensure the safe production.
In various industries where gas, petrochemical, metallurgy, steel, coking, electricity, etc. exist in the presence of flammable or toxic gases, gas detectors are used in hazardous locations where flammable or toxic gases are present. In order to ensure property and personal safety, it is necessary to use a gas detector to continuously detect the content of the lower limit of the detected gas in the air for a long time. The gas detector requires a specific standard gas calibration for a specified period of time. Please link to the standard gas for details.
