The PA500 series analyzer accurately detects changes in a certain component in binary or quasi binary mixed gases (i.e., only one component changes in the mixed gas). The gases that can be detected include hydrogen (H2), carbon dioxide (CO2), argon (Ar), helium (He), etc. As long as the thermal conductivity of one component in a mixed gas is different from that of another component, thermal conductivity technology can be used to detect this component in the mixed gas. Depending on the gas being detected, the range can be from high ppm to 100%.
Hanks Company uses a lossless thermal conductivity sensor to detect the thermal conductivity of gases. This type of sensor has a high sensitivity, low heat capacity, and non consumable component, which does not require protection. To achieve accuracy and detection range that conventional thermal conductivity sensors cannot provide, there is a microprocessor inside that provides signal processing, and the instrument requires almost no maintenance.
The built-in sampling pump can extract sample gas from a low-pressure source or naturally extract sample gas. Use needle valves and flow indicators to control the sample gas flow through the analyzer.
PG500 can detect two types of gases. It combines the detection function of PA500 with the detection function of electrochemical primary cell for oxygen (O2), with a detectable oxygen (O2) concentration range from 100ppm to 100%, depending on the operating conditions.
