Household CO Alarm KGD-JM-203 with Electrochemical Sensor Fast Response Time and Adjustable Alarm Concentration
Household CO Alarm KGD-JM-203
Product Introduction
The Household CO Alarm KGD-JM-203 is installed in places such as kitchens, bedrooms, and bathrooms where CO leakage may occur. When the concentration of CO in the air exceeds the set value, the detector will be triggered to alarm and send out audible and visual alarm signals with a volume of up to 85 decibels to remind people of the danger. It can help people receive early warnings, stay away from harm, and ensure personal safety. It is widely used in household kitchens, agricultural trade markets, various oil depots, chemical plants, gas stations, and other fields.
