The SCUFA (Self-Contained Underwater Fluorescence Apparatus) is an accurate, simple-to-use and versatile submersible fluorometer for chlorophyll and dye tracing applications. The SCUFA has been designed to operate in a wide range of concentrations and environmental conditions. The capability to program sampling intervals via the Windows Interface Software and the automatic range control enable the user to configure the SCUFA for any type of profiling or moored deployment.
Accuracy
‧Typical temperature fluctuations in natural waters can result in significant changes in fluorescence values. The SCUFA, with its integrated temperature probe and software, automatically corrects fluorescence data of temperature effects.
‧Turbidity can also cause errors in fluorescent readings. The SCUFA II, and III utilize a dedicated secondary channel for turbidity measurement
that provides valuable data for potential correlation and correction.
‧User-selectable 0V and 5V values result in optimal range selection and improved resolution of analog data.
‧Superior ambient light rejection eliminates the effects of sunlight and allows the SCUFA to be used in surface waters without the need for
external pumps or light shields.
Simplicity
‧The SCUFAs menu-driven software provides the interface for instrument configurations and data analysis. The software walks the user
through easy-to-follow steps for functions such as calibration and data collection.
‧The Auto-Ranging capability provides an extremely wide dynamic range, allowing the SCUFA to be used in dramatically different environments without ‧manually changing gain settings or going over range.
‧The SCUFAs solid secondary standard allows the user to verify instrument calibration quickly and easily and to re-calibrate if necessary.
‧The optional Copper Anti-Fouling Screens enable unattended deployment for extended periods without the performance suffering from the
effects of biofouling.
Versatility
‧0-5V and RS-232 signal outputs are standard features, so the SCUFA can be mated to a variety of CTDs and data collection devices.
‧Open optics eliminates the need for a pump, but with the optional flow-through cap, a pump can be used.
‧The SCUFA can be programmed for user-defined sampling rates and times with the purchase of the Internal Data Logging (IDL) Package.
IDL also reduces power consumption through the use of Sleep Mode between sampling intervals.
