Important note
The following response data does not constitute part of the product specification and is for reference only. For the most accurate measurement results, the gas being detected should be used to calibrate the instrument.Gas calibrates the instrument.
The table below shows the response change of MICROpeL when exposed to a range of gases and vapors at the same %LEL concentration. Data is obtained experimentally and is expressed relative to the methane signal( =100 ) indicated. Testing was completed with 2.5% vol. CH4 (based on the now obsolete EN50054 LEL value, 50% LEL CH4).
Based on the LEL values specified in EN 50054 (now obsolete) and EN60079-20-1:2010, the relevant response data is shown in the table below.
