Features & Benefits

  • Methane-optimized catalytic bead sensor provides increased stability over time
  • Sensor response and clear times in less than 15 seconds – Reduces gas usage for bump testing and calibration
  • Greater accuracy and repeatability within changing environmental conditions – Temperature, humidity and pressure
  • Digital sensors offer increased RF (radio frequency) immunity – Eliminate false alarms from radios
  • Accurate CO readings from 0-2000 ppm
  • Industry-first CO/NO2 combination sensor with wide range and fast response times
  • Increased methane sensor poison resistance decreases down time and frequency of sensor replacements
  • End-of-sensor life warning gives advanced notice of failing sensors
  • Sensor life that greatly exceeds industry average
