Are these sensors compatible with natural gas/methane?

Asked by: melectron
Thank you for your inquiry, this unit is designed to work with Dry, clean, non-corrosive gases only. If you're measuring natural gas or methane, we would recommend that you use a intrinsically safe sensor.

Does this sensor come with a meter as shown in the picture?

Asked by: haochey
Thank you for the inquire. The meter would be a separate purchase

What does (3 wire) output mean?

Asked by: shannon007
This is a 3 wire voltage output device. Wiring is as follows: The positive side of the power supply is connected to the V+ terminal. Both the negative side of power supply and the negative output signal are connected to the V- terminal. The positive output signal is connected to the OUT terminal.
