The SCM3 Carbon Monoxide Detector (CO Detector) offers several features and benefits to field technicians:

• Fast electrochemical sensor helps you find CO sources like cracked heat exchangers or breached flue stacks.
• Calibrate to ambient quickly with ZERO button.
• Audio and visual alarms (with MUTE function).
• Alarm rate increases as carbon monoxide concentration increases.
• MAX hold to help you zero in on the source.
• Bright-blue backlit dual-display to test in dark crawl spaces.
• Magnetic hanger for hands free testing.
• Auto Power Off (APO) to save battery life (easy to disable).
• Battery check with % of battery life left displayed.
• Use with optional AOXP2 pump for flue gas testing.
