潛入式水下螢光計
SCUFA™ Submersible Fluorometer

TURNER DESIGNS SCUFA 潛入式水下螢光測定儀是一種精確靈活簡單易操作的水下螢光測定儀, 可應用水中葉綠素和染料追蹤研究. SCUFA 可在各種的濃度範圍和環境下使用, 利用 Windows 介面軟體設定採集間隔和自動範圍控制功能, 可使 SCUFA 用在任何層面的實驗研究工作或設置於固定場所連續監測與資訊蒐集.

準確性:

在自然水體中溫度的變化會顯著影響螢光值的改變. SCUFA 透過內置溫度感測器和軟體程式, 能自動修正溫度對螢光資料的影響.

	濁度同樣會導致螢光讀數產生錯誤, SCUFAIII 型配備專門的第二頻道來測量濁度, 提供潛在而有價值的相關和修正資料 (右圖).
	用戶可選擇的 0 到 5V 範圍, 產生最佳測定資料和提高類比資料的解析度.
	先進的環境光抑制功能, 消除了日照的影響並允許 SCUFA 不需外接取水泵浦或遮光罩.

操作簡單:

	功能表操作的軟體提供儀器設置和資料分析的連接, 軟體有相應的步驟提示用戶完成如校正和資料獲取等功能.
	自動定量程式功能提供一個極為寬廣的動態範圍, 使SCUFA 可應用於各種不同環境而無需人工設定或超出測定範圍.
	固態標準校正片使儀器的校準快速和簡單.
	可選擇的銅質防污染保護網能夠有效提高儀器的長期連續使用的準確性.

多功能:

	標準 0 ~ 5V 和 RS-232信號輸出, 可匹配多種 CTD 和資料獲取設備.
	開放式光路不需水泵即可工作, 如用取水泵浦抽水時則可配流動蓋.
	使用者透過選購的內置資料蒐集功能可設定採樣頻率和時間, 內置資料蒐集器具有睡眠模式可節省電力.

Self-Contained Underwater Fluorescence Apparatus
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 SCUFA's 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 SCUFA's 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.
