Overview

The SCM4 Carbon Monoxide (CO) Detector has a very fast reaction time, and measures CO in parts per million (ppm). Its electrochemical sensor is fast enough for walk around tests. The SCM4 responds to changes in CO levels in real time: Zero the unit outdoors away from any source of CO (will not zero if CO levels are higher than 5ppm) - Enter the structure, walk around and watch the display, then move toward the area of highest concentration to find the CO source

Features

• Field replaceable CO sensor is easy to install, comes pre-calibrated and lasts approximately 2 years
• Sensor calibration: Factory calibrated at 17 ppm CO and 200 ppm CO
• Range: 0 to 1,000 ppm - 0 to 2,000 ppm (less than 5 minute exposure time
• Initial accuracy at 73 degrees is plus / minus 9 degrees at less than 75% relative humidity
• 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 button)
• 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 after 15 minutes to save battery life (easy to disable)
• Battery check with % of battery life left displayed
• Battery: 9 volt with 150 hours typical life
