Note 1) IAQ application, accuracy is defined after minimum 3 times calibration for 3 weeks.

     2) +/- 2% is added for absolute measurements for uncertainty of calibration gas mixture unless the measurement is done with certified calibration mixtures.

3) DC Supply should be regulated , low noise power source for best accuracy.,

4) < 0.2mA of Low Power Consumption model

Product Derivatives with Functions

T-110-3V has various output TTL-UART, I2C, ALARM, AVO (or PWM is selectable as option) and 1.27pitch 10pin side hole connector. Non-Periodic Manual Calibration (10’ MCDL) are executable by sending ‘Low Signal’ be to pin-10.
