In most building environments, it is prudent to have gas monitors in place to detect and control Carbon monoxide (CO) levels. This E3Point Single Gas Monitor comes with a CO sensor cartridge for the base unit that is factory calibrated and ready to use right out of the box. The main standalone unit can be wall mounted with screws at various heights and includes a built-in audible alarm. Onboard relays let you activate ventilation fans and strobe. For dual gas monitoring, select a remote unit with optional sensor cartridge and relay it back to the main unit. The E3Point’s plug and play features mean you can easily detect your choice of toxic and combustible gases, thus saving both time and money.

Key Features:

  • Works as a standalone unit
  • Advanced factory calibrated smart cartridge technology allows E3Point to detect CO, NO2, O2, H2, H2S, CH4, or C3H8. Swap outs are super simple
  • Patented Reflex and smart cartridge technology periodically bump tests and monitors cell response time
  • Advanced electrochemical (for toxic gases) and catalytic bead (for combustible gases) sensor performance
  • Two onboard relays can activate fan or strobe light
  • Onboard sounder; Audible alarm range of 85 dBA at 3 meters (10 ft)
  • Analog 4-20 mA output
  • Response time of T90 < 50 seconds; with ECLAB T90 < 240 seconds
  • Electrical Certifications in US (ANSI/UL 61010-1) and Canada (CSA C22.2 No. 61010-1)
  • Remote sensor includes housing and cartridge; also easily replaceable

Potential Building Environments: Parking structure, loading dock, transport terminal, golf cart maintenance / battery charging area, maintenance garage, hospital / ambulance bay, fire / police station, boiler room, battery charging rooms and hydrogen tanks, commercial kitchen, indoor stadium / arena.
