C3 Submersible Fluorometer
998-2300 Rev. H Page 4
1. Introduction
1.1 The C3 Submersible Fluorometer is manufactured according to users’ optical
specifications with one, two, or three optical sensors ranging in wavelengths
from deep ultraviolet to infrared. Each optical sensor is designed with fixed
excitation and emission filters. The C3 Submersible Fluorometer comes with a
factory-installed temperature probe and can be configured with a pressure
sensor for depth measurements up to 600 meters and/or a wiper to minimize
biofouling. The C3 Submersible Fluorometer Windows based user interface
allows for easy calibration of each sensor, digital data reporting, data logging
and digital or analog export of data.
