Explore the instruments
Pore pressure, movement and discharge on embankments and tailings storage facilities — instrumented, logged, and telemetered to the people who act on it.

Wall movement, pore pressure and blast energy measured on site and returned to the geotech office to keep crews safe.

Strong-motion and broadband instruments, structural arrays and the software that locates the event and tells the people who need telling.

Stations, radar and rain gauges feeding the road, aviation and site systems that have to make a call before the front arrives.
Trusted by industry leaders
Water authorities, miners, utilities, universities and government agencies across Australia run ESS instruments in the field.









The ESS group
One company behind every division
Four specialist divisions, one solution provider. Whichever name is on the instrument, it comes from the same Melbourne workshop, the same calibration lab and the same engineers who answer the phone.
- GeosystemsGeotechnicalInstruments for dams, mines and civil works
- GreenspanWater qualitySensors built to live in the river — turbidity, sondes, level and telemetry.
- Seismology Research CentreSeismologySeismographs, networks and the software that finds the epicentre.
- WeathertechMeteorologyWeather stations, rain gauges and radar — paddock to national network.
