We are an established South African based manufacturer and supplier of quality and affordable capacitance-based soil moisture monitoring equipment designed to optimize the management of soil water. Our products also include self-developed dedicated irrigation management software and full agronomy support.


The use of capacitance soil moisture probes is seen as a vital tool in improving on-farm irrigation management. The need for a robust, reliable and affordable capacitance soil moisture probe lead to the start of AquaCheck in 2002. After a few years of research and development, production and marketing were launched in 2005.

Today AquaCheck is recognised across the world as a reliable, robust and affordable capacitance-based soil moisture probe manufacturer. From our manufacturing plant, based in Brackenfell, Cape Town, South Africa, we have manufactured and sold over 60 000 probes in more than 20 countries across five continents.
Supported by the specialist knowledge and dedication of our agronomists, engineers, manufacturing team and support staff, AquaCheck have added telemetry, self-developed irrigation management software and agronomy support to its product line.

Our products have applications in agriculture, sports and recreation, mining and environmental management.

For more information on our products, refer to Our Products section.


We have an experienced and competent team which spans manufacturing, agronomy, software development and support. Our approach, which focuses on teamwork, has resulted in a high rate of employee retention. Many of our team members have remained with the company since its inception in 2002.
