Comment: All data in % LEL are LEL values as specified by the IEC.
1) Gas transmitter calibration at 50 % of the full-scale deflection.
2) Relative change of the signal at 50 % LEL (Dräger PIR 7000) resp. at 5 % vol. (Dräger PIR 7200).
3) The measured value response times may vary with other approved substances. Depending on the accessories used longer response times are possible.
