The manual piezometer probe, also known as a beeper probe or light probe, is a simple and portable solution for spot measurements of water levels in boreholes, wells and tanks.
The water level is measured by lowering the sensor into the structure: the probe emits a light signal and a buzzer when the sensor reaches the water level. The height of the water can then be read on the measuring cable, graduated to the millimetre for a simple and precise measurement.
The switch has 3 positions: off (position 0), battery test (position I) and measurement (position II).
