Bullet-Proof Performance!

The new AirSense™ Model 350 delivers reliable and hassle-free carbon dioxide (CO2) sensing. You know us as a leader in CO2-sensing, but the Model 350 is the strongest, most reliable, and most versatile product we have ever offered! 

This unit can be used in LEED applications!

The Model 350 employs our patented single button calibration, which makes field calibration a snap... but please do not be disappointed if you never need to use this easy calibration feature, because the Model 350 is engineered to give you the best stability available in a low-cost PPM CO2 sensor!

Conservation
Efficiency
Performance
About 15% lower cost! Reliability! Energy-Efficiency!

The AirSense™ Model 350 CO2 sensor does more for less! Priced far below the cost of its predecessor, the Model 350 offers expanded versatility for a lower price!

The AirSense™ Model 350 draws less energy than previous generations of CO2 sensors! This is thanks to our integrated Power Management Software, which operates with such efficiency that you will save money and reduce your carbon footprint!

The AirSense™ Model 350 comes standard with our AdaptiveSense Technology (AST), which reduces the long term drift that has characterized NDIR sensors up to now. Specifically designed to reduce service calls, the Model 350 sets a new standard for quality!

It’s not just for CO2 sensing any more!
The AirSense™ Model 350 is the successor to our tried-and-true Model 310e. This next generation product allows you to order only those features you need, saving you money!

In addition, new features such as an:

  1. audible alarm,  
  2. humidity (RH) sensor, 
  3. carbon monoxide (CO) sensor, 
  4. volatile organic compound (VOC) sensor 

All these sensors are now available for very little cost!  Win more bids with the versatile and inexpensive Model 350!

Made in America
AirSense always has been, and always will be made in America!
