Meter PLF40
Areas of use PLF40
9.1
The PLF40 is used to determine electrical conductivity, salinity and temperature and combines the advantages
of a compact design with the precision and comfort of a lab meter. Simultaneous conductivity, salinity and
temperature measurement, high measurement accuracy, multi-functional display, integrated data logger and a
robust aluminum housing mark this meter.
Composition PLF40
9.2
The PLF40/Set includes the meter with accessories and the conductivity sensor LTC0,35/23-K010-U. This
combination meets the requirements to determine the conductivity; electro-chemical process as per EN
27888:1993. When connected to the sensor, the meter will capture the conductivity in µS or mS, the
temperature as well as the salinity simultaneously.
All Meinsberg Conductivity Sensors are available with fixed cable and connector BK. The description of the
used conductivity sensor is listed in the separate instructions for use for the sensor.

Configuration of the fixed temperature
The measured conductivity value can be put out temperature-compensated. For this, the temperature of the
measuring and calibration media must be measured or set up as a fixed temperature.
If the fixed temperature is activated, it is used for temperature compensation.
