The Remote Carbon Dioxide (CO2) Storage Safety Alarm is designed to protect individuals near stored carbon dioxide. This fixed gas safety monitor measures CO2 levels and detects leaks in order to protect facilities from overexposure.
CO2 alarms are critical in restaurants, breweries, wineries, beverage dispensing areas, dry ice storage, laboratories, cultivation facilities, or anywhere more than 100 lbs. of CO2 is stored or produced. 
*Please note with the purchase of any Remote CO2 Storage Safety 3 Alarm, a surge protector is required for safeguard and longevity of the monitor*
