Technical Data

The conversion factors for the standard EX and the specialized EX-H and
EX-M sensor are the same except for EX-H and Nonane and o-Xylene. The conversion factors
for these two vapors are therefore especially mentioned in the table.
Oxygen
The oxygen sensor has built-in temperature compensation. However, if temperature shifts dramatically,
the oxygen sensor reading may shift. Zero the device at a temperature within 30 °C (86 °F) of the work
place temperature for the least effect.
