ZA-3002 Portable Gas Purity Analyzer

Portable H2 Gas Purity Analyzer

Sent Email :

ZA-3002 portable gas purity analyzer adopts thermal conductivity sensor with high stability and high precision. According to the difference in thermal conductivity of gas, it can measure the content of random one gas of two mixture gases accurately and quickly. Unique technique of wide-range temperature compensation is adopted, so as to guarantee the measurement precision of instrument. It can monitor gas purity during generator operation and normal operation in hydrogen station. It can measure the gas concentration in the gas replacement process when generator shuts down and starts up.


  • Thermal conductivity sensor with high stability and high precision .
  • Full-range temperature compensation, quick response, high precision and steady performance .
  • Real-time curve display.
  • High precision and good stability.
  • Operation and control by color touch screen .
  • Storage and printing the measuring data.
  • Intelligent display of electricity quantity and intelligent charging protection.
