PCE-WMM 50-ICA is a wall-mounted air quality carbon dioxide meter that uses diffusion to monitor carbon dioxide (CO2) gas levels and ambient temperature (ºC / ºF) indoors. This indoor air quality carbon dioxide meter features an alarm-activated potential-free contact that can, for example, activate a fan to reduce CO2 gas concentration in the room.

- CO2 gas measurement range: 0 ... 50,000 ppm
- Temperature measurement range: 0 ... +45 ºC / +32 ... +113 ºF
- IP54-rated enclosure on sensor and remote display units
- 2 adjustable alarm thresholds
- 3- to 4-digit remote display (depends on range)
- incl. ISO Calibration Certificate

The Air Quality Meter Gasman-SO2 is a unique gas meter which protects against a specific gas, inflammable or toxic. The Air Quality Meter warns with a penetrating alarm and an optical signal (useful in case when there are loud noises in the surroundings) of the existence of dangerous gas concentrations and shows on screen the value of the gas measurement. The Air Quality Meter fulfills all the European and international norms, even ATEX and UL standards.

- Non-rechargeable, 1-year battery
- For SO₂ (Sulfur Dioxide)
- Dust and water resistant - IP 65/67
- 0... 20 ppm
