Carbon Dioxide Meter PCE-WMM 50

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

The PCE-WMM 50 alert meter consists of two parts: the sensor unit and the remote display unit. This allows for safe monitoring outside the exposure zone.

By monitoring CO2 concentration, the indoor air quality meter helps protect workers against the health hazards associated with CO2, a colorless and odorless gas used in the food, metal, chemical and waste management industries.

HIGHLIGHTS
- CO2 gas measurement range: 0 ... 50000 ppm
- Temperature measurement range: 0 ... +45 ºC / +32 ... +113 ºF
- IP54-rated enclosure on sensor and remote display units
- 2 adjustable alarm thresholds
- Alarm-activated potential-free contact can, for example, activate a fan to reduce CO2 gas concentration in the room
- 3- to 4-digit remote display (depends on range)
- Audible and visual alarm signals
