ZA-3002 Penganalisis kemurnian Gas Portabel untuk H2, H2, CO2 Gases

ZA-3002 portable gas purity analyzer for H2, H2, CO2 gases

Brief Introduction
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 accurately and quickly measure the content of random one gas of two mixture gases. Unique technique of wide-range temperature compensation is adopted, so as to guarantee the measurement precision of instrument.
