image001HT Portable water level meter 

HT Water Level Meters are part of the standard equipment for the ascertainment  of ground water levels. These mobile units are characterized by their simple, fast and solid acquiring of water level. With the variety of models available, you have the possibility to select the appropriate unit according to your in- dividable requirements in cable length or operating convenience. All HT Water Meters are equipped with visual signal- ling on water contact, as a standard feature. Optionally, all units can be ex- tended to include acoustic signaling and a bottom sensor to sound the depth of the drilling. Our measuring units have been in operation all over the world for many years now and are a guarantor for robustness and precisely measured values in rough field conditions.


For mobile measurements of water level and temperature in wells and groundwater observation pipes.

The Water Meter type 110 is an ideal measuring appliance for the manual measurements of water level and water temperature in wells, boreholes, tanks and groundwater observation pipes. This device is especially designed to ascertainment of temperature profiles and water level of the well.  Thanks to its high-quality processing in a sophisticated operation, our unit offers you extreme robustness, highest operating comfort and absolutely precise measurements. The optionally available bottom sensor further extends the cap ability of the Water Meter type 110 to measure additionally the depth of the groundwater well.


For mobile measurements of level, temperature and conductivity/ TDS in wells and groundwater observation pipes.

The Water Meter type 120 – LTC is an ideal instrument for the manual measurements of conductivity, TDS and temperature profiles as well as for water level detection in wells, boreholes, tanks and groundwater observation pipes. In cause of the high quality, the instrument offers robustness, comfortable usage and accurate measurements for the level detection and acoustic and an optical LED signal is given.  Thanks to the small sensor diameter of 20mm, measurements in wells from 1 inch are feasible. The Display with integrated backlight guarantees a clear readability also under unfavorable light conditions.


For depth sounding of firm ground at the bottom of boreholes, groundwater wells and surface water.  • Stable triangular frame • Cable drum of high-tensile acrylic resin,  resistant to cold conditions  • Generous hand crank and grip • Holder for depth gauge weight
