What are LEL and UEL? How to Convert to PPM? - Karf&Scoot

Jun 21, 2021· % vol = 10 ppm % vol = 1 ppm. The % LEL value can be used with the gas name as each gas has its own variable LEL value. If we look it on the example of hydrogen sulfide, which is both toxic and flammable gas: 100% LEL = 4% vol = 40,000 ppm H 2 S 50% LEL = 2% vol = 20,000 ppm H 2 S 10% LEL = % vol = 4,000 ppm H 2 S.

Analog Gas Sensor(MQ2) (SKU:SEN0127)

So given the values you reported, the estimated PPM of combustible gases is between 330 and 950 PPM. The Lower Explosive Limit (LEL) of propane for example is %, or 21000 PPM, so you are well below that threshold. However, the permissible exposure level is 1000 PPM, so I am almost certain that your potentiometer needs to be adjusted.
