PCE-WMM 100 Carbon Dioxide and Oxygen Meter
Air Quality Carbon Dioxide Monitor PCE-WMM 100
CO2 alarm system for carbon dioxide and oxygen / Adjustable alarms / 4-digit LCD display / Consists of a main unit and a remote unit / Relay contacts / Analog output
The PCE-WMM 100 CO2 alarm system consists of a main unit and a remote display. The PCE-WMM 100 CO2 gas detector is used to measure carbon dioxide and oxygen levels at a specific location. The CO2 alarm system protects people from odorless CO2 gas and also warns of low oxygen levels in the air. The gas alarm system displays the measured values on an LCD screen. The PCE-WMM 100 CO₂ alarm has two relays that can be used to control warning lights or audible alarms. In addition, the CO₂ alarm has a built-in audible alarm that emits an 80 dB sound signal in the event of an alarm.
The warning device is used wherever CO2 may be released. This includes warehouses, breweries, wine cellars, or restaurants. The main unit is IP54-rated. Four LEDs on the front panel provide information about the system’s status.
