The Fieldpiece SCM3 Carbon Monoxide Detector is a standalone carbon monoxide detector (CO detector) with a very fast reaction time. The Fieldpiece SCM3's electrochemical sensor is specific to carbon monoxide (CO). The Fieldpiece SCM-3 is a rugged instrument can help you hunt down sources of potentially life-threatening, poisonous gas. Carbon monoxide (CO), a product of combustion, is an odorless, colorless gas.

Faulty combustion equipment is one source of this dangerous gas known as the "silent killer". The Fieldpiece SCM3 standalone carbon monoxide detector measures CO in parts per million (ppm). Use it for walk-around tests to help pinpoint sources of CO indoors. Measure CO ppm in flue gas using the optional Fieldpiece AOXP2 pump.

CO Exposure Effects
CO ppm Effects
(effects can vary significantly depending on age, sex, weight, and overall health.
stay in an area of high concentration of CO; Get outdoors and call emergency Response)
9 ppm Minimal. Max Allowable Concentration for eight hours (EPA and ADHRAE)
35 ppm MAX for continuous exposure for one hour (EPA and ASHRAE)
50 ppm Max for eight hour (OSHA)
100 ppm Trips installed CO detectors. UL2034 specified a max exposure of 100 minutes
200 ppm In two to three hours: slight headache, tiredness, dizziness, nausea.
UL2034 specified a max exposure of 15 minutes
400 ppm In one or two hours: Frontal Headaches.
In three hours: Life threatening.
UL2034 specifies a max. exposure of 15 minutes
800 ppm In fourty five minutes: Dizziness, nausea, and convulsions
800 ppm In two to three hours: Death
