RA701 Hydrogen analyzer
RA701 Hydrogen purity analyzer
The RA701 hydrogen comprehensive analyzer is mainly used for measuring the purity, humidity, oxygen content of hydrogen during the normal operation of hydrogen cooled power generation units and hydrogen production station equipment, as well as the carbon dioxide and oxygen content in the gas replacement process.
Purity sensor adopts a high stability and precision thermal conductivity sensor, which accurately and quickly measures the gas purity in the gas according to the different thermal conductivity of the gas. The unique wide range temperature compensation technology ensures the measurement accuracy of the instrument.
Humidity sensor adopts Vaisala’s high-performance dew point transmitter as the humidity measurement unit of the entire instrument
