Product Description
The SRAQ-D622-2 sensor uses NDIR technology to detect the CO2 concentration in the air and transmits a corresponding 0 10 V analog output
signal. The device has 1 meter cable and can be easily mounted to a wall or other flat surface. Uses include factory floors, laboratories, server rooms,
office and commercial buildings or other areas where CO2 concentration is a concern.

Output Correlation
The 0 10 V analog output are correlated to actual gas concentration, the formula to their correlation is:
Formula: X / (10 V / Y ppm) = Actual concentration
X is the actual output voltage value
Y is the maximum range
Notes
1. Please confirm the polarity and the rated power supply before powering ON the device.
2. Turn the RS level to the TTL level and then connect it to the computer for proper data.
