The Saltiphone is a sensor for measuring wind erosion. Wind erosion can degrade a soil's fertility as soil particles are blown away, conversely in coastal areas wind erosion can strengthen sand dunes and stimulate vegetation growth.

Particles hitting the microphone produce high frequency noise, which can be distinguished from other noises caused by wind and rain. Frequencies of about 8 KHz are amplified and used to determine saltation.


  • Ideal for erosion research & practical applications for example in sand dunes
  • Measures wind erosion using an acoustic measuring principle
  • The impact of sand grains can be measured, counted and saved.
  • Stainless steel housing
  • Height adjustable (0-50 cm)

  • Built in waterproof aluminium housing for electronics
  • Individually calibrated sensors.

Soil Research Laboratory Equipment

From the field to the lab our equipment delivers accurate results time and time again

Soil moisture characteristics (pF), aggregate stability, particle size distribution, penetration resistance, water infiltration and permeability, carbonate content, soil colours are all important soil research parameters to monitor the behaviour of pollutions in soil.

Whereas some equipment such as the double ring infiltrometer is constructed for onsite use, mostly this equipment is used in the laboratory.

Unique instruments such as the wet sieving apparatus or the Calcimeter, the only instrument currently capable of performing carbonate content analysis on multiple samples are worth a special mention.
