Product description

Parameters

　　Product Name: nitric oxide standard gas (NO standard gas, NO2 standard gas and nitrogen oxide standard gas)

　　Packing Description: 4L, 8 litre aluminium alloy cylinder, in order to protect the gas quality, it needs to be equipped with stainless steel bottle head valve

　　Use:

　　Produces 1-50 ppm, 50-2000 ppm, 2000ppm- percent standard nitric oxide gas, formulated according to customer requirements. Multicomponent and nitrogen oxide standard gases, including nitric oxide, nitrogen dioxide, and other 2~20 components, can be formulated.

　　No standard gas mainly used in petrochemical process control instrument calibration and testing, petrochemical product quality control, environmental monitoring, vehicle emissions testing, various factories exhaust gas detection, geological exploration and seismic monitoring, metallurgical analysis, gas calorific value and experimental analysis, the chemical fertilizer industry instrument calibration etc..

　　Matters needing attention：

　　Nitric oxide is a high pressure filling gas. It should be used after decompression and pressure reduction. When the concentration is high, it is recommended to be used with stainless steel pressure reducer. When using standard gas of nitric oxide, the residual pressure in the bottle shall be kept at 0.5MPa, and the minimum remaining pressure shall not be less than 0.25MPa. After use, the bottle valve should be closed to ensure the quality and safety of the gas. No standard gas in the transport storage and use should be strictly classified and piled up, combustible gas and combustion gas stacked together, not close to the fire and heat, should do not near the fire, not oily wax, not exposure, do not throw, do not hit, no arc or arc in standard gas cylinders of nitric oxide NO, rough handling.
