This low-cost pocket-type meter checks the existence or concentration of CO in the environment and displays the reading in ppm. The large dual digital LCDgive a quick simultaneous overview of the Current and Max Carbon Monoxide levels. It has a long life & reliable electrochemical CO sensor that can be used in residential, commercial and industrial settings to monitor CO levels in parking garages or rooms with gas furnaces, central heating furnaces, kerosene heaters, oil burners, stores, water heaters, ranges ovens, stoves or fireplaces.

The audible alarm (beeps at 45db) calls for prompt attention when the exposure safety limit exceeded, adjustable alarm is preset at 25ppm.

Top design housing, surround with rails to help air ventilation for quick and accurate response. In addition, it can automatically calibrate at 0ppm or manually calibrate at 100ppm/500ppm carbon monoxide standard gas.

CE marking is marked on the product's body, you are 100% safe while using our product!
