HI-88703-02
HI-88703-02 is a high accuracy meter that benefits from Hanna’s years of experience as manufacturer of analytical instruments.
The HI-88703-02 turbidity bench top meter is specially designed for water quality measurements, providing reliable and accurate readings on low turbidity ranges.
This instrument has an EPA compliance reading mode which rounds the reading to meet EPA reporting requirements. 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. When user prepared standards are used, calibration points can be modified. The HI-88703-02 features complete GLP (Good Laboratory Practice) functions that allow traceability of the calibration conditions. The last calibration points, time and date can be checked. 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.
The HI-88703-02 meets and exceeds the requirements of USEPA and Standard Methods.
