Water Level Meter Mini - With Start / Stop System

This water level meter is perfect for measuring the water level. The meter gives a clear acoustic and light signal when it comes in contact with a liquid substance after which the depth can be easily read. This water level meter has a start/stop method to limit the drop in water level and can be used with the Royal Eijkelkamp peristaltic pump.
Start/stop system for the Eijkelkamp peristaltic pump, in order to limit the drop of water level
More accurate analyses 
Fewer soil particles into the filter pipe
Sound and light signal when you reach the water level
Easy to carry
Available in two variants
 
Description
The water level meter is part of the standard equipment for measurement of groundwater level. It is provided with a stainless steel probe with a diameter of only 14 millimetres, which is connected to a measuring tape with centimetre graduation. The probe gives clear light and sound signals when the probe comes into contact with a conductive liquid. The user can lift the cable slightly to stop the signal. The depth can then be easily read via the measuring tape. The product is accurate to approximately centimeter.
The purpose of the start/stop method of preliminary pumping is to limit the drop in water level such that the inflowing water draws many fewer soil particles into the filter pipe, which will result in much more accurate analyses. This water level meter can be connected to the Royal Eijkelkamp peristaltic pump.
