Measuring is based on the principle, that when mixing gases with different thermal conductivities their mixture has a thermal conductivity dependent on the concentration of its constituents. Thereby portions of individual gases can be determined.
We recommend to do a calibration at one point with a pure gas or bottle gas. After the gas is applied to the device wait until the concentration is stable. The calibration process can be started via the keys on the front of the analyzer or via RS232 command. Then it takes ten seconds for the actual calibration.
We recommend a calibration, resp. a check of the calibration if one of the following criteria is met:
To find out the appropriate time between calibrations, we recommend to begin with a more frequent check of the calibration.
The time between calibrations can range between:
We offer 0-100 Vol.% H2 in N2 (and many other background as Ar, CO2, O2, CH4…)
Helium is similar with the ranges:
Any range in between is available.
The analyzer need pneumatic connection to the sample gas. It is designed for wall mounting.
The analyzer comes with cables with open ends. Connection to 24V is necessary for operation.
Connection of 4-20mA output, relays and RS232 are available and can be connected as required.
