1) The measuring function for the explosion protection according to EN 60079-29-1 is proven, see EC-Type Examination certificate
BVS 05 ATEX E 143X and associated additions.
2) The LEL values were used according to IEC 60079-20-1. Other LEL values may apply for the device settings at the location of use.
3) Typical tolerance: ±5 %.
4) When the following substances are measured at concentrations above 70 % LEL, the deviations of the measured values exceed the
permitted deviations in accordance with EN 60079-29-1.
