The SMART-Sensor LCD, performing with excellence since its initial release in
2004, has just been significantly improved. An integrated CO2 sensor option has now
been added to further compliment the feature-rich design of this flexible and economical
product. The new CO2 sensor has a convenient auto-calibration feature that
establishes a baseline CO2 level for any space. So it calibrates on its own! The new
CO2 model adds yet another desirable option to the SMART-Sensor's all-in-one
packaging, eliminating the need to install multiple sensing devices in a given space.
