Carbon monoxide sensor including connecting cable 1.5 m long for CO measurements in air range: 0 ... 300 ppm range: 0 ... 5000 ppm range: 0 ... 5 Vol.% • Examples from the range of applications: Measurements in air conditioning systems, air purifiers, oxygen rectifiers, greenhouses and oxygen incubators. ! A correction value can be stored in the ALMEMO® con nector plug to compensate for the natural ageing of the probes, so optimum output characteristics can be ensured for the whole operating life. 11/2025 • We reserve the right to make technical changes.
