Eco Detection

You can’t manage what you can’t measure

Our world-first monitoring technology measures water quality in real-time, collecting and sharing complex environmental data that can be translated into more sustainable, actionable results.

We provide a managed monitoring solution to Government organisations, NGOs, research institutes, regional councils and industry. This includes installing and maintaining sensors, as well as delivering sensor data and regular reporting. Our technology was initially developed for military purposes in searching for fertiliser-based explosive devices.

GreyScan’s Eureka Prize winning defence product, the ETD-100, is now available globally. During 2020, in response to COVID-19, the company added to its portfolio with the development of a product to detect SARS-Cov-2 and future viruses. Building on the core technology for environmental monitoring, Eco Detection has been proven in field trials and we’re proud to be significantly ahead of anything in the market, providing a level of accuracy that water scientists could only dream of – until now.

We’re passionate about using our tech to help industry, government and organisations better monitor, measure and manage freshwater quality; not only helping our customers, but improving freshwater environments around the globe.
