Product Information

Get faster carbon monoxide (CO) readings with the Extech CO10!


This pocket-size carbon monoxide meter displays CO levels from 0 to 1,000 ppm on an easy-to-read backlit display. An audible alarm starts at 35 ppm and beeps continuously above 200 ppm, giving you clear and unmistakable indications when CO is present at dangerous levels.


The Extech CO10 features a stabilized electrochemical gas specific (CO) fast-response sensor. So this device is specifically designed to detect carbon monoxide and do it fast. Results have an accuracy level of ±5% or ±10ppm, leaving little room for doubt in your readings.


Using the Extech CO10 is easy thanks to its convenient one-button on/off design. This meter also features Max Hold and Data Hold buttons, so you can capture and record readings with ease.


An Auto Power Off function shuts the meter down when not in use, conserving battery life.


This carbon monoxide meter is ideal for use in the following applications:

  • Ambient air safety checks on residential appliances
  • HVAC service on furnaces and hot water heaters
  • Home inspections
  • Industrial environments where the accumulation of CO is possible



  • 9V battery
