The measuring cell of the PS-Light-2 does not come directly into contact with the measured medium and therefore does not have to be cleaned regularly of deposits (e.g. lime).
Since, as is generally known, air is not conductive, elaborate electronic overvoltage protection can be dispensed with.
PS-Light-2 engages in a continuous measurement operation and can easily be autonomously supplied with solar panels (e.g. 50 W panel, at 5-minute measuring interval and 1/4 hourly transmission).
Last but not least:
The measurement system is available in several versions PS-Light-2 sensor with or without an LCD, PS-Light-2-LCD with an integrated data collector and as a compact data transferring station PS-Light-2-Modem (including remote data transmission).
