Standard Gases
Every Gas Analyzer required to calibrate once a while (period calibration is preferred), that will maintain analyzer remain its stable analysis ability. Also for assume the Gas Detector still has the function to detect the gas leakage, calibration gas is required to use.

Accuracy Calibration Gases are requested to be the standard for Gas Analyzers and Gas Detectors to do period calibration. Even more, some Gas Analyzer Manufacturer recommend their customers to do Liner Calibration once a period (use several concentrations’ calibration gases). So you will know how Calibration Gases important to the Gas Analyzers and Gas Detectors.

 

Jing De could manufacture the standard gas upon demand of our customers. Our primary standard meets ± 1% NIST Traceable / USA Gas Companies ( NIST = USA National Institute Standard and Technology ) or Taiwan ITRI made standard gas. And our Certified Standard is Traceable to ± 1% or ± 2% of Taiwan or world famous manufacturer made Standard Gases.

Jing De had got ISO 9001 certificate on Jan. 10, 2002, we provide customers the standard gas by highest precision and stability, so our customers are able to calibrate their Gas Analyzers and Gas Detectors by these precision and stability Standard Gases. Please refer the gas mixture specification that we offered:.........
