Specifications obtained under laboratory conditions of gas flow, temperature and humidity. Field performance is dependent on the correct installation procedures being followed, environmental conditions, frequent sensor cleaning and regular calibration. Some of the sensors have cross sensitivity. Details are subject to change without notice. Please contact us for more information.
