With long battery life and large buttons for ease of use with gloves, the dSense portable carbon monoxide meter works perfectly as a personal safety alarm unit in hazardous environments, or wherever carbon monoxide is produced, stored, generated and used.

The large LCD readout gives a quick overview of the current CO level and the 80 dB audible alarm calls for prompt attention when the short-term exposure safety limit is exceeded.

The meter uses a high-accuracy electrochemical cell for detection and is easily calibrated at both 0ppm and 500ppm points with reference gas.

peace of mind

Replaced a meter that we had which disappeared one day. Gives me peace of mind with an external house generator which sent CO into our basement once.

George Baker

it works very well i get a consistent reading of 8 to 10 at work but it seems to sky rocket upwards (160, 184) when i quickly move it to a new spot spot then goes to 0 and stays or when outside a heavy breeze passes by don’t know if it’s actually co in a windstream or just a quick current of different temperature air

"Easy to install, easy to set up, and easy calibration - just what I was looking for."
