Gastec CMCD-200 Carbon Monoxide and Carbon Dioxide Detector

The compact body permits accurate measurement of CO and CO₂ in buildings and offices. Can simultaneously measure carbon monoxide and carbon dioxide, quickly and accurately.

Features

The product is small and light, weighing a mere 600 g. It can thus be carried around with ease.
The indication accuracy for CO is +/-1ppm, putting it in the high reliability class (within the range of 0-10 ppm).
The energy conservation switch reduces the drain on the batteries.
The lighting switch enables you to easily read the measured results even in a dark location.
The CO sensor can be replaced by the customer.
The product can be powered by three kinds of power supply (dry batteries, nickel-hydrogen rechargeable batteries, and AC supply).
24-hour measurement can be performed (by using the optional AC adapter).
Incorporates a logging function.

Applications

carbon monoxide and carbon dioxide, quickly and accurately.
