General Features


The WATER-PAM chlorophyll fluorometers achieve outstanding sensitivity by fluorescence detection with a particularly red-sensitive photomultiplier combined with special preamplifier electronics. In this way, detection limits for suspensions down to 0.1 µg chlorophyll/liter are achieved.

Damage to the susceptible photomultiplier tube by external radiation is averted by an automatic switch-off circuit. Consequently, the photomultiplier tube is shielded from external light during measurements.


A further feature of WATER-PAM chlorophyll fluorometers is that they can be operated independently from line connection and computer by the battery-powered PAM-CONTROL unit.

The same PAM-CONTROL unit functions as a physical interface between measuring unit and computer for operation of the WATER-PAM by the WinControl software.
