This voltage tester is a special test tool for warning of dangerous voltage in flooded electrical systems, shafts, basements and industrial plants.

In the case of flooded basements, feed-in from house connections or industrial plants can cause life-threatening voltage in the water many meters away from the connection point. If the fuse elements are flooded, they can no longer offer protection. Feeds from solar systems or storage devices can be live even when the utility fuse is switched off. In flooded cellars, the water can be very dangerous. In flooded maintenance shafts, faulty insulation in connections and sleeves can cause life-threatening tensions in the water many meters away from the fault location.

Due to its structure, the DSP-HW 2 is suitable for a wide variety of test tasks:

  • Checking banisters and similar objects protruding into the water
  • Check the water in the flooded areas
  • Check the water while installing a pump
  • Checking flooded maintenance shafts
  • Check residual water after the water level has dropped to a few centimeters

Its waterproof housing enables use under harsh working conditions.
Thanks to its two display systems (LED and LCD), the DSP-HW 2 is easy to read in any environmental condition.
Its continuous function monitoring and the integrated self-test offer maximum security.
