Martindale CO190 Carbon Monoxide Meter

The Martindale CO190 Carbon Monoxide Meter is capable of measuring carbon monoxide particles in the air from 0 to 1000ppm with an accuracy of ±5% or ±5ppm with a resolution of 1ppm. Additionally, there is a temperature measurement facility enabling measurement of air temperature between -20˚C and 70˚C with an accuracy of ±0.8˚C and resolution of 0.1˚C.

Readings for both parameters are simultaneously displayed on the Martindale CO190’s backlit digital display and a maximum reading and data hold function are also available which is ideal for using the meter in awkward situations where line of sight cannot be maintained.

Additionally, an audible alarm sounds when concentrations are detected above 35ppm (adjustable by the user) and this becomes a continuous tone above 200ppm. A higher frequency tone is produced when concentrations over 1000ppm are detected to indicate a greater danger.

The Martindale CO190 comes supplied with batteries and a soft pouch and is covered by a two-year warranty.
