• Accurate and long term stable thermal conductivity measurement
• High sensitivity e.g. 0-0.5Vol.% H2 in N2 range; Low noise <10ppm H2 in N2
• Precise linearization for the gas mixtures as H2, He, CO2, CH4 in N2 or Ar and N2 in Ar on board
• Customized linearization with polynomial up to sixth order
• Multi Gas Mode allows sequential indication of up to 15 binary mixtures
• Isolated 4-20mA output, expandable; free set of start and end within 100 Vol.% range
• Classic 2-point calibration or simple one-gas calibration
• Free set of display indication (ppm or Vol.%) at a resolution up to 1ppm
• Cross sensitivity compensation by feed in of external signal and internal calculation
• Fast response with a T90-time of less than 1 sec (depending on flow rate)
• Pressure proof (20bar) and vacuum leak tight stainless steel (LF316i) gas duct
• Three isolated relays for indication of alarms and instrument status
• RS 232 excess to all values and parameters
• Digital output with 1ppm resolution over the whole 100Vol.% rangePC-based service program simplifies all settings, linearization and calibration
• Small and robust transmitter in Al-housing for field use (protection class: IP65)
