The CO90 Carbon Monoxide Meter from Martindale is rapid responding and is an ideal device for checking safety.
A beeper will sound and speed up with any CO concentration and will become a continuous tone when the level is above 200ppm which is the recommended 15 minute short term exposure limit.
The max and hold buttons allow one reading or the highest over a period of time to be displayed on the screen.
