Thoë in Seawater

Meet THOË®, your solution for cost-effective seawater monitoring. Providing enhanced data collection, improved quantification, and robust functionality down to 1000m, it’s a leap forward in aquatic analytics.

Initiated in the early 2000s, Goro-Nickel began operations in New Caledonia using innovative ore processing technology, resulting in high-concentration metal solutions requiring careful treatment.

By 2010, effluent plume dispersion monitoring began via spot sampling.
To improve quality, cut costs, and solve logistical issues, comparative studies validated the superior efficiency of Diffusive Gradients in Thin films (DGTs) over traditional methods, paving the way for an automated solution.

Thus, THOË® was born in 2018.

Introducing THOË®, revolutionizing freshwater monitoring. Enhanced data collection, improved quantification, and resilient operation.
Dive into savings and superior analytics with THOË®.

Beginning in the early 2000s, Goro-Nickel introduced a novel ore processing technology, generating high-metal-concentration solutions needing careful management.

In 2010, spot sampling was employed for effluent plume dispersion monitoring.

The use of Diffusive Gradients in Thin films (DGTs) showcased superior efficiency, leading to the inception of an automated device.

THOË® in 2018, bringing about a revolution in freshwater monitoring.
