Clemco CMS4

The CMS-3 monitor detects carbon monoxide in the breathing-air supply and triggers audible, visual, and vibratory alarms when CO is detected in concentrations of at least 10 parts per million. The alarms alert the operator to an unsafe condition.

Requirements for Operation

Battery installed in the CMS-3
25 ppm calibration gas, calibration cup and connector
Grade D or ambient-air breathing-air supply for the abrasive blast operator
Thorough familiarity with the CMS-3 instructions

Additional Information

Digital liquid crystal display (LCD)
Audible, visual, and vibrating alarms
Low battery alarm
Sensor fail alarm
Replaceable sensor and battery
Blast operator can work independently. No need to rely upon others to warn operator or take action when monitor alarms. No need for remote alarm; each user is individually protected for instant awareness of a hazardous condition.
Unit is small, lightweight, and conveniently worn inside blast respirator. Requires no external connections or hoses.
Unit can be calibrated in minutes, is easily installed, and easily removed.
Long-life, economical easy-to-replace sensor with estimated sensor life of 2 years.
Unit uses small commonly-available lithium easy-to-replace battery with estimated life of 3000 hours.
Microprocessor controlled with digital read-out for accurate readings.
