EPP-50V is a push-in type vibrating wire piezometer, designed to measure pore water pressure in soft soil/clays and landfills. It has a pointed cone at one end and drill rod threads at the other end. When threaded into a drill rod, the piezometer can be pushed into soft soil directly. The cable attached to the piezometer is passed through the drill rod. Thread options are EW drill rod thread or M28.


  1. Reliable, accurate, low cost and simple to read.
  2. Protected against lightning spikes.
  3. Easy installation in soft soil, clays and landfills in earth fill dam foundations, ideal for soil fill work.
  4. Hermetically sealed under a vacuum of 0.001 Torr; stainless steel construction.
  5. Thermistor provided for additional temperature measurement.
  6. Can measure negative pressure
