I presently have one supplier that can provide a method of measurement by introducing a sample to a flame of known temperature, the sample causes a controlled explosion. The resulting increase in temperature is proportional to measure of combustables, thereby an indication of LEL. This approach is proven but relatively expensive to install. Electrochemical and Infarred technologies have been discounted since they apparently only measure constituents of the gas, not the entire mixture. Suggestions?
