The HI 88713 turbidity bench meter meets and exceeds the requirements of the ISO 7027 standard.
HI 88713 is based on an optical system which guarantees accurate results, long term stability and minimizes stray light and color interferences. It also compensates for variations in intensity of the LED, limiting the need for frequent calibration.
Depending on the measured sample and needed accuracy, normal, continuous or signal averaging measurement can be selected.
A two, three, four or five-point calibration can be performed using the supplied standards. Calibration points can be modified when user prepared standards are used.
The HI 88713 turbidity bench meter has complete GLP (Good Laboratory Practice) functions that allow traceability of the calibration conditions.
The HI 88713 turbidity bench meter has a user-friendly interface with an easy to understand, graphic LCD. Comprehensive contextual help is available at a simple key press. Furthermore, a tutorial mode of operation guides the user step by step through the analysis process.
Up to 200 measurements can be stored in internal memory. Data can be transferred to a PC via optional HI 920013 USB cable and HI 92000 Windows® compatible software.
Order Information: HI 88713-02 (230V) is supplied with sample cuvettes and caps (6), calibration cuvettes, silicone oil, tissue for wiping cuvettes, power adapter and instruction manual.
