Hyperion Turbidity

A compact & robust package ideal as a standalone sensor, for ROV and AUV integration or used as part of a multi-sensor array and data logger system.

Optical Turbidity sensor

The new Hyperion Turbidity is essentially 2 sensors in one.

The first is a “classic” turbidity sensor, a nephelometer that uses a 90° beam angle, for low turbidity levels (0 to 1,000 NTU). The second, for high turbidity levels (1,000 to 6,000 NTU) uses an Optical Backscatter (OBS) arrangement (~120° beam angle). Intelligent sampling and use of a 24 bit ADC eliminates the need to gain switch at higher turbidity levels. The optical head is very compact, measuring just 20mm in diameter and with a full ocean depth rating lends itself to OEM type solutions.

Offered as standard in a 6,000m depth rated, titanium housing the Hyperion Turbidity Instrument has a wide range (9-28V DC) isolated power supply, data output up-to 16Hz on RS232 and RS485 or Modbus RTU communication protocols. Hyperion offers an industry-leading dynamic range with no adjustment of gain settings required.

Hyperion Fluorometers can be supplied in a more rugged form that includes Acetal protection rings, a shaped anti-snag connector cover and a Kevlar weave protected cable.
