Note 1：Sensor is designed to measure in the range 0~2000ppm (PWM),0-10000ppm (UART) with specified in the table accuracy. Nevertheless exposure to concentrations below 400ppm may result in incorrect operation of ABC algorithm and shall be avoided for model with ABC ON.
Note 2: In normal IAQ applications, accuracy is defined with -10°C -50°C ,0-85%RH and after minimum two (2) ABC periods of continuous operation with ABC on. Some industrial applications do require maintenance. Contact Cubic for further information.
Note 3: Specification is referenced to certified calibration mixtures. Uncertainty of calibration gas mixtures (±2% currently) is to be added to the specified accuracy for absolute measurement.
* The above features and specifications are preliminary version. Some contents might be changed before the product is mass-production.
Applications
Fresh Air System
