    TSM400-1-CP is a multi-parameter sensor that supports the 1-Wire protocol. The sensor measures the concentration of carbon dioxide and atmospheric pressure. Both basic sensor elements, for carbon dioxide and pressure, used in the device are digital. This ensures high measurement accuracy and longterm stability. The basic sensing element for atmospheric pressure is factory calibrated and it does not require any lifetime recalibration. Automatic calibration is available for carbon dioxide measurements. TSH400-1-CP is housed in a slim plastic enclosure. The bottom part of the enclosure is suitable for installation on standard flush-mounted/cavity wall boxes ø68mm, with installation openings on 61mm.

    CO2 measurements:
    Range: 400 to 5000 ppm
    Accuracy: ± (40 ppm +5 %)
    Resolution: 1 ppm
    Calibration: Automatic, if the sensor is exposed to fresh air for more than 30 minutes.

    Barometric pressure measurement:
    Range: 10 to 1200 hPa
    Accuracy (min): ±1.5 (25°C at 750 hPa)
    Accuracy (max): ±2.5 (-20°C to + 85°C, 300 to 1100 hPa)
    Resolution: 1 hPa
