FLUOROMETER FOR SURFACES WATER

Flow-through field fluorometer for surface waters

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.
