Martindale CO190 Carbon Monoxide Meter



Martindale CO190 Carbon Monoxide Meter

The Martindale CO190’s a tough high performance, carbon monoxide meter suitable for on-site use. The ergonomic designed and optimised for easy handling and reliable results in difficult applications.
The clear LCD display shows the reading in ppm, with an audible beeper that speeds up with CO concentration, becoming a continuous tone above 200ppm.

The default alarm threshold’s set at 35ppm and can easily adjust from 0 to 1000ppm. For readings over 1000ppm the alarm beeper sounds continuously with a high frequency tone. The LCD screen will display OL to indicate an over range reading and has a low battery indicator. Battery life time’s around 200 hours under normal operating conditions.

Max & Hold buttons allow for the current reading, or the highest reading over a period of time to be captured. Together with the audible tone, these features make the CO190 ideal for use where access or line of sight’s difficult.

The CO190 carbon monoxide detector’s supplied with batteries, soft carry case and manual.
