The testo 317-3 ambient CO meter is small, lightweight, and provides fast and easy CO testing

With programmable settings for both visual and audible alarms, as well as hands-free operation, ambient CO testing during furnace and boiler service and maintenance, weatherization audits, or home inspections has never been easier.

An exclusive self-test mode provides worry-free operation, as it will always verify that the CO sensor is functioning, anytime and anywhere, without the need for test gas.  In addition, the self-check will ensure accurate CO measurements, without the need to “zero” out the unit in a fresh air environment. It detects the presence of carbon monoxide (CO) in ambient air and warns the user if potentially harmful CO concentrations are reached.
