LT1 Oxygen Analyzer Electronics

The LT1 is an universal useable, microprocessor-based O2 analyser for direct measurement of O2 concentration of gases in hyperstoichiometric ranges  ( ? >1). In connection with the Lambda probe LS1 it can be used in:

  • Combustion exhaust gases
  • Industry exhaust gases
  • Oven atmospheres
  • Process gases

For recording burnable gas components  (CO/H2), the Combination probe KS1D can be used additionally, with the following benefits:

  • Linear probe signal (D/C [mA] with fixed physical zero-point
    No special test gases needed, automatic balancing with ambient air (21 Vol. % O2)
  • Preciseness of measurement better than 0,2 Vol. % O2 over the whole range of measuring 0…21 Vol. % O2
  • No gas conditioning needed
  • No reference gas needed
  • Setting time <20s on 90%-value (T90) with gas extraction device (GED) , 450 mm long
  • No influence of measuring  temperature on preciseness of measuring
  • No temperature control of ZrO2-measuring cell needed
  • Automatic adaptation of cell temperature on cell internal resistance (Compensation of aging)
  • Measuring gas temperature up to 800 °C with metal extraction or up to
    1.400 °C with ceramic extraction
  • Means no ignition source inside flue gas channel – TUV approval existing
  • Intermittent operated measuring gas pump with definitiob of optimal pump running time
  • Easy to handle
  • Low-maintenance
