Gas detector PCE-WMM 100
Carbon dioxide and oxygen warning device / Adjustable alarms / 4-digit LC display / Consists of main and remote unit / Relay contacts / Analog output
The PCE-WMM 100 CO2 detector consists of a main unit and a remote unit. It is used to measure carbon dioxide and oxygen at a fixed location. Therefore, it warns of a concentration of odorless CO2 and also of a low oxygen content of the air. The measured values are displayed on an LCD screen. The detection unit has two relays that can be connected to lights for visual alarm indication or speakers. In addition, it has a built-in, acoustic alarm, which, depending on the concentration of the gas, emits an 80 db sound signal.
The warning device is used wherever CO2 may be released. This can be in warehouses, breweries, wine cellars or restaurants. The main unit is partially waterproof with a waterproof rating of IP54. Four LED indicators provide information about system status.
