Note 1：Sensor is designed to measure in the range 0~2000ppm (PWM),0-10000ppm (UART_TTL/I²C) 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.
