BMT 932 now available with partial pressure display

New Ozone Monitor displays the ozone partial pressure (mPa) according to DIN ISO 1431-1 and ANSI D 1149-07

The OZONE MONITOR BMT 932 now is available with a second display showing the partial pressure of the ozone in millipascal (mPa). It is calculated from the ozone content in ppmv (parts per million, volume by volume) and the pressure inside the test chamber. This pressure is measured via a thin tubing leading the pressure from the chamber to the OZONE MONITOR BMT 932.

At a given and constant ozone concentration (ppmv) the ozone partial pressure (mPa) can be significantly different if the ozone tests are made at places with different geodesic heights and at different weather conditions. Between e.g. Hamburg and Munich differences could be 10%, and between Los Angeles and Mexico City they could even be 25%.
