1. a signal output indication.

2. the dual signal output (analog output, and TTL level output);

3. TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller)

4. analog output 30 ~ 50mV voltage, the higher the concentration the higher the voltage;

5. carbon dioxide has a high sensitivity and good selectivity;

6. has a long life and reliable stability;

7. rapid response recovery characteristics;

8. the probe can plug design for easy testing.
