atmosphere to diffuse inward. See Figure 3.

Combustible Gas Sensor

The LEL sensor detects combustible gas and vapors in the atmosphere

with a catalytic platinum element. The reaction of gas with oxygen on

the catalyst causes a change in the resistance of the element, which is

converted by the GX-86A into a reading of gas concentration.

The LEL sensor responds to a wide range of gases; see Appendix A

for the Relative Response Chart.

Oxygen Sensor

The O

sensor is an electrochemical cell, which reacts to the oxygen

in the atmosphere, producing a current proportional to the oxygen

concentration. This current is converted by the GX-86A into an

oxygen reading.
