Key Features
High accuracy and excellent stability. For outdoor environments, calibration should not be necessary for 10 years or more. (Contact AirTest for long term performance data.)
Fast response. T90 = 6 seconds
All sensors have two point calibration adjustment to tow points.
Radiation shield to eliminate effects of solar radiation, rain snow and wind.
For harsh and polluted environments a protective environmental coating is available. Ideal for coastal areas or marine applications subject to salt spray.
