Flow-through field fluorometer for surface waters

 Diameter 160 mm Height 170 mm
Usage: Direct immersion in water flows (0-20 m depth), springs or as laboratory fluorometer for fast sample measurements. Can be as well used with quick-connect fittings and 6 mm tubings. Up to 4 light sources cover the whole optical spectrum. Casing : stainless steel. Optional: aluminium.

The sonde connects through a 4-wire signal cable to a waterproof box hosting a datalogger and 1 or 2 batteries. The datalogger provides power, timing, clock and data storage capability. The signal is transmitted in digital form. The box can connect to any PC through the RS232 interface. For unattended work, the datalogger stores as many as 4 x 60,000 samples and water temperature (0.01°C accuracy) on a Compact Flash card.

A recent datalogger version features following advantages: LCD display on 2x16 characters, USB interface instead of RS232, microSD card instead of CF, and optional GPRS modem for remote data access through the web.
