selected that is not compatible with the selected lamp the following symbol will appear
to highlight the incompatibility.
PID Lamp (2, 3 & 5)
An alternative lamp to the Krypton 10.6eV (standard) can be
purchased, fitted and selected. A tick '

Should a Lamp be selected that is not compatible with the selected
gas the following symbol will appear to highlight the incompatibility.
Unit Selector (1, 2, 3 & 5)
The P photoionisation detector can be selected to
measure VOC's in either ppm (Parts per million, by volume),
ppb (Parts per billion) or mg/m
3
(Milligrams per cubic meter).
NB: the ppb option is available on the P 5000 and is upgradeable on the 1, 2 and 3000 versions.
Data Log Memory Alarm (2, 3 & 5)
P has been designed to continuously store data once
the memory has reached its full capacity (8 Mb) it will
automatically begin to over write previous readings. An alarm can be set to inform the user that this is due
to happen giving the user time to download any data that may be over written if they wish to do so.
