The Extech CO30 Carbon Monoxide Monitor is a three‐in‐one instrument that monitors and measures temperature and humidity in addition to carbon monoxide. The fully calibrated instrument will provide years of reliable service in a number of applications that require monitoring of CO in common areas such as indoor work places such as warehouses that use propane or gasoline-powered fork lifts, manufacturing plants with temporary heating units and gasoline-powered appliances, boats, planes, and RVs.

The Extech CO30 measures carbon monoxide concentration from 0 to 999 ppm, air temperature from 32 to 122˚F and relative humidity from 20 to 90% RH and alternately displays the results on the LCD display. A bright, tri-colored LED changes from green (under 10 ppm) to yellow (10 to 29 ppm) to red (over 30 ppm) indicating the CO range. An adjustable alarm sounds a loud beeper when the adjustable CO setpoint has been exceeded. The CO30 can be wall mounted or used on a desktop close to areas of concern.
