The Martindale CO190 is a tough high performance, carbon monoxide meter suitable for on-site use. The ergonomic designed has been 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 is set at 35ppm and can be easily adjusted 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 is 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 is difficult.

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