Carbon Monoxide Meter (Co) With Smart Sensor SCM4

The Carbon Monoxide Meter (Co) With Smart Sensor SCM4 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.

Field-replaceable CO sensor; Advanced three-pin sensor measures 0 to 1000 ppm CO; Calibrate / Zero SCM4 to ambient quickly with the ZERO button; Audio and visual alarms w/mute; Bright-blue, backlit dual-display with MAX and real-time measurements displayed; Magnetic hanger for hands-free operation; Auto Power-Off (APO).

Features and benefits include: 

• Field-replaceable CO sensor; Advanced three-pin sensor measures 0 to 1000 ppm CO
• Calibrate / Zero SCM4 to ambient quickly with the ZERO button
• Audio and visual alarms w/mute; Bright-blue, backlit dual-display with MAX and real-time measurements displayed
• Magnetic hanger for hands-free operation; Auto Power-Off (APO).

The "Walk-Around" Test: 

• 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
• Move toward the area of highest concentration to find the CO source

Features And Benefits To Field Technicians:

• Field-replaceable CO sensor
  - Easy to install
  - Lasts approximately two years
  - Comes pre-calibrated
• 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

Fast and Easy Sensor Replacement

The SCM4 and ACM4 replacement CO  sensor (RCM4)
comes electronically calibrated, and can be purchased
directly from your distributor. Simply plug in your new
sensor and your SCM4 and is automatically
calibrated to factory standards. With normal use, the
RCM4 lasts for approximately two years. Sensor life is
highly dependent on exposure to contaminants, and
repeated exposure to contaminants will shorten the
life of the sensor.
