The Lambda probe LS2 consists out of an electrochemical cell, made of Zirkonium-dioxide-ceramic for direct O2 measurement of exhaust gases in hyperstoichiometric range Lambda > 1.
In connection with the Lamtec Lambda Transmitter LT2, the probe becomes a simple "plug-and-play" O2 analyzer - without having to calibrate with test gas. If higher accuracies are desired, then a calibration with test gas is possible.
The measurement is directly in the wet flue gas. The probe connection is carried out via plug, so that the handling is very easy.
