Hyperion fDOM

Valeport’s Hyperion fDOM (fluorescent dissolved organic material) sensor delivers high performance measurements of DOM in a compact & robust package ideal as a standalone sensor, for ROV and AUV integration or used with as part of a multi-sensor array. Measurements of fDOM help to understand the health of all aquatic habitats, including coral reefs and marine benthic communities.

Offered as standard in a 6000 m depth rated, titanium housing, the Hyperion Fluorometer has a wide range (9-28 V DC) isolated power supply with data output up to 32 Hz via RS232, RS485 or Modbus communications.

Hyperion Fluorometers can be supplied with sensor guards and a shaped anti-snag connector cover. If required, a more robust Kevlar weave protected cable can be supplied.
