The 050-8-0182 eSense Low-Temperature CO2 Transmitter (formerly known as the SE-0036) is designed to measure ambient CO2 levels outdoors in any weather. The heating element maintains a constant temperature for both the sensor and air samples, giving consistent measurements over time.
  • Measure CO2 as low as -22°F
  • Built-in Heating Element
  • IP65 Outdoor Rated Housing

The use of outdoor CO2 measurement is as a baseline to compare against indoor CO2 levels for LEED points is referenced in the LEED standard for Outdoor Air Delivery Monitoring EQ1.2.

The transmitter uses an IP65-rated housing with a built-in heater. The heater ensures that gas samples entering the CO2 sensors are not only warm enough for sensing but also at the correct moisture level. The CO2 levels are then read by the NDIR carbon dioxide sensor and transmitted via industry standard 0-10V or 4-20mA signals to an HVAC system.

The eSense uses ABC (Automatic Baseline Correction) calibration. This algorithm automatically corrects for long-term CO2 level drift, making it virtually maintenance-free.


This device will NOT meet requirements for CO2 safety monitoring which requires a Fixed/Wall mounted, hard-wired alarm per the NBIC, NFPA, or IFC regulations. Refer to our CO2 Safety Products page for devices that meet your needs.
