Gas detector for the detection of carbon dioxide (CO2) / 2 adjustable alarm limits /
4-digit digital display / Built-in alarm device / Easy wall mounting
The PCE-WMM 50 is a wall-mounted diffusion gas detector for monitoring carbon dioxide (CO2) levels and ambient temperature (ºC / ºF) indoors. This indoor air quality meter has a voltage-free contact, which is activated by an alarm and can, for example, start a fan to reduce the concentration of CO2 gas in the room.
The PCE-WMM 50 alarm meter consists of two parts: the sensor unit and the main unit, which can be fixed on a wall. This allows safe monitoring for leakage outside the exposure zone.
- CO2 gas measurement range: 0 ... 50000 ppm
- Temperature measurement range: 0 ... +45 ºC / +32 ... +113 ºF
- Enclosure with IP54 sealing class on sensor unit and main unit
- 2 adjustable alarm limits
- The voltage-free contact, which is activated by an alarm, can for example start a fan to reduce the CO2 gas concentration in the room
- remote control with 3 to 4 digits (depends on range)
- Audible and visual alarm
