Portable hand-held device for determining the water level and for depth sounding up to 200 m
Fine mechanical, fully automatic measurement procedures
Mechanical counter to display the groundwater level in m and cm
Light weight and compact design
Comfortable, handy and light:
The TLG is characterised by its light weight and easy handling. The TLG is held over an open groundwater measuring point. By flicking the crank handle, the lock is released and the weighted cable is lowered at a constant speed. Once the weight reaches the water table surface, the TLG locks the rope drum. The distance covered by the steel rope can be easily read on the 5-digit roller counter in meters and centimeters. Subsequently, the solder is recovered from the measuring point by means of the crank handle without any great effort. Thanks to the metal weight, measurements performed through the liquid level will be carried out all the way to the very bottom.
