The CMS-3 is a field, in-helmet, CO monitor/alarm for air respirators and can be moved from helmet to helmet. Connector and test gas are not included with this monitor.
This monitor detects the presence of CO inside Apollo supplied-air respirators. If CO exceeds 10 ppm, the US limit set to meet Grade D quality breathing air requirements*, it triggers a warning light and a high-decibel audible alarm.
This monitor is for blasting and painting contractors in field operations. NIOSH has approved the use of the CMS-3 with Clemco respirator models Apollo 20, 60, and 600.
The CMS-3 offers a full range of features, including:
Digital liquid crystal display (LCD)

Over 3,000 hours of operation from 1 battery
