Monitor Water Health

Spotter Water Quality

Starting at $17,130

Add dissolved oxygen and temperature sensors to your Spotter Platform to monitor subsurface water quality in real time. Track underwater ecosystem health to improve research, aquaculture site assessment, and environmental compliance.

What is the Spotter Platform?

Spotter is a modular, rapidly deployable marine sensing platform that delivers real-time surface and subsurface ocean data to power better decisions.

What is Spotter Water Quality?

A turnkey solution to monitor underwater temperature, dissolved oxygen, and other water quality parameters in real time. Ships globally, deploys quickly, and transmits water quality data instantly.
