ThisAirSense™Model 310e CO2 sensor reads carbon dioxide concentrations in the parts per million (ppm) range, and is ideal for applications ranging from conference rooms to fitness gyms.

Fresh air contains 350-400 ppm CO2. Human respiration and combustion by-products from furnaces, fireplaces, and household appliances can easily raise indoor levels above 2000 ppm. With your AirSense™ Model 310e CO2 Monitor, you can watch CO2 levels rise as people enter a room.

    According to the National Institutes of Occupational Safety and Health, increased levels of CO2 may contribute to "Sick Building Syndrome" and symptoms such as hyperventilation, headache, dizziness, shortness of breath, and drowsiness. The AirSense™ Model 310e CO2 monitor provides a continuous, accurate reading of indoor CO2 levels, making it easy to maintain an optimum level of fresh air.

    The AirSense™ Model 310e carbon dioxide (CO2) meter is easy to install and support. Measurement output is via a 4 - 20mA current loop or a 0 to 10 volt interface. A completely isolated power supply eliminates any ground loop or electrical interaction problems when multiple units are connected to the same controller. Low power power consumption makes the AirSense™ line of CO2 Monitors perfect for battery-operated or other power-sensitive applications.

    The Model 310e’s single gas verification makes field calibration a snap, and its superior design means significantly longer calibration intervals. Unlike other CO2 Monitors, its simple user interface has no complicated menus: all maintenance and calibration operations are easily performed even on units with no display.

    This carbon dioxide monitor is a leader in cost-effective versatility.

.   The clear, bright 0.4" high liquid-crystal display option is readable from any angle for installations where local annunciation of the CO2 concentration is desired. For direct control applications, the relay option can be configured to open or close above the set point and is easily adjusted in the field. For plenum sampling requirements, the popular duct option is easy to install.

The high-performance AirSense™ Model 310e uses an advanced Non-Dispersive Infrared (NDIR) sensoring systems to assure quick and reliable CO2 response.
