Product Launch: Kompakt Piezometer

Following an extensive R&D program, Geomotion Australia are pleased to announce the launch of Soil Instruments’ new range of vibrating wire Kompakt Piezometers.

The new Kompakt is a cost effective piezometer to complement the market leading W4 and W9 instruments. Although cost has been designed out, the Kompakt maintains high quality engineering with key features such as hermetic sealing and temperature monitoring.

The Kompakt Vibrating Wire Piezometer provides accurate measurement of pore water pressures.

The transducer is designed to handle pressure ranges from 0 to 500 kPa. It incorporates an over voltage surge arrestor that offers protection from a lightning strike.

The piezometer is fitted with a low air entry stainless steel sintered filter.

An integral thermistor for temperature monitoring is included.
