The first kind:
The purity of hydrogen is measured by an oxygen analyzer, and the analysis range is 0-2% or 0- 1%, in which the purity of hydrogen is obtained when the oxygen content decreases 100%.
The oxygen purity is measured by an oxygen analyzer, and the analysis range is 0- 100%. The measured value of oxygen content is the oxygen purity.
The general principles of the above two analyzers are electrochemical.
The second type:
The purity of hydrogen is measured by an oxygen analyzer, and the analysis range is 0-2% or 0- 1%, in which the oxygen content is 100% minus the measured value, that is, the purity of hydrogen is generally based on the electrochemical principle.
The oxygen purity is measured by a hydrogen analyzer, and the analysis range is 0-2%, in which the hydrogen content is 100% minus the measured value, which is generally the principle of thermal conductivity.
No matter which analyzer is used, it takes a certain period of calibration, usually 6- 12 months. The analytical instruments of hydrogen stations in many power plants can not correctly display their purity values, which brings security risks to operation.
Tianjin Qi Xin Energy Technology Co., Ltd. sells American Gebana brand analyzer, and the model used in the hydrogen station of the power plant is oxygen analyzer O2X 1 hydrogen analyzer XMTC Company provides standard sample gas while selling the instrument, and at the same time sends technicians to conduct on-site calibration training to guide maintenance personnel to calibrate; Solve the worries of its instrument use.
