• For extractive gas analysis
  • For quality and process monitoring
  • For continuous determination of the concentration of single gas components like e.g. H2, CO2, O2, He, Ar, CH4, N2, NH3,CO, SF6 in binary gas mixtures in the gas-, food-, insulating glass- and thermal treatment-industry


  • High sensitivity e.g. 0….0.5 Vol.% H2 in N2
  • noise < 10 ppm H2 in N2
  • Durable measuring cell
  • Sequential measurement of 15 binary gas mixtures due to multi gas mode
  • Offsetting the cross sensitivity of an interfearing component possible
  • Quick response time (T90 < 1 s)
  • Comfortable menu and operater navigation at calibration and parameterisation
  • Classic two-point calibration or one-point calibration
  • RS232-access to all (measuring) data and parameters


  • Precise and long term stable gas analysis according to the thermal conductivity measuring principle
  • Microprocessor based
  • 128 x 64 point graphic display
  • Operation via 3 keys or PC-based service program
  • Small robust design in aluminium housing for field operation (protection class IP65)
  • Linear electrically isolated current output 4….20mA, start and end point concentration freely selectable
  • 3 configurable relays for alarm message and device status
  • Precise linearisation for binary gas mixtures like e.g. H2, He, CO2, CH4 in N2 or Ar in the permanent storage; additional customer specific linearisation with polynomial of 6th order Indication in ppm or Vol.%, resolution adjustable up to 1 ppm
  • Pressure resistant (20 bar) and vacuum leak-tight gas path out of stainless steel (SS316Ti)
