Great idea. I was thinking that a combustible sensor must be calibrated before use. Without a known concentration of gas being applied to the sensor the unit will not be accurate and will give wonky/false readings. How do you do your bump test or calibration? Would you use a 50% methane or a pentane equivalent? Haz gvince4

Hey haz, I would guess a caveman simple way to calibrate or tune that device might be to build a test air chamber out of a fully enclosed glass fish tank,etc. Then try putting various amounts/types of oil,etc in the controlled environment tank till you reach some useful & usable data. Hope this helps:)
