Description

Hyperion Turbidity is essentially two 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 a 24-bit ADC eliminate the need to gain switches 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 6000m depth-rated titanium housing, the Hyperion Fluorometer has a wide range (9-30V DC) isolated power supply, data output up to 16Hz and RS232 communications.
