1.Using high-quality dual-panel design, with power indicator and TTL signal output instructions.

2.The switching signal having a DO (TTL) output and analog output AO.

3.TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module ).

4.The higher the voltage , the concentration of the analog output voltage is higher.

5.For methane, natural gas has a good detection sensitivity.

6.There are four screw holes for easy positioning.

7.Dimensions : 32 (L) * 20 (W) * 22 (H).

8.Rapid response and recovery characteristics.
