List Price for 0-100 Vol% H2 in N2: 3400 €
If you are not sure whether this unit is suitable for your requirements, please contact us for product advice.
- How it Works: 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.
- Ease of Use: Just connect the device to the process stream, switch on. After 30 min (heat up time) the device is ready for use.
- The measurement are based on the thermal conductivity. Please keep in mind that there some restrictions.

About function:
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.
About calibration:
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:
- After bringing the device into service
- On a regular cycle, depending on the precision aimed for.
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:
- several month for a measuring task in the Vol.% range
- days to weeks for a measuring task in the sub-Vol.% range
- directly before every measurement if highest accuracy is needed
- When the situation of the measurement regarding pressure, temperature or gas flow changes
About measuring ranges:
- The smallest range for low H2 concentration is 0-0.5Vol.% H2 in N2.
- The smallest range for high H2 concentration is 98-100Vol.% H2 in N2.
We offer 0-100 Vol.% H2 in N2 (and many other background as Ar, CO2, O2, CH4…)
- The smallest range for low He concentration is 0-0.8Vol.% He in N2.
- The smallest range for high He concentration is 97-100Vol.% He in N2.
Helium is similar with the ranges:
Any range in between is available.
About operation:
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.
