CO and O2 Monitors
For Supplied-Air Respirators

 

  • Electrochemical Sensors

  • Audio and Visual Alarms

  • LCD Display of Gas Concentration

  • Continuous Monitoring

  • Menu Driven Controls

  • Menu Driven Calibration

  • Alarm Relay Contacts

  • Fault Relay and Visual Fault Alarm

  • Flowmeter Plus Low Flow Fault Indication

  • Alarm Acknowledgment Capability

  • Optional 4-20 mA Outputs

 

The ISA-300RAL respiratory air line monitor automatically and continuously monitors compressed air lines for CO and activate audio and visual alarms if the concentration of the contaminant rises above a preset limit. In addition, the O2 version also continuously monitors compressed air for oxygen content, and activates alarms if the oxygen content varies from a preset range. It provides protection for the employer and the worker using supplied-air respirators by warning personnel of a carbon monoxide hazard or oxygen deficiency/enrichment condition.

 

The instruments are designed to monitor for a maximum concentration of 10 ppm CO in Grade D breathing air as specified by Federal OSHA guidelines
