PRELIMINARY EXAMINATION

HI 88703 is a high accuracy, meter that benefits from Hanna’s years of experience as manufacturer

of analytical instruments.

The HI 88703 is especially designed for water quality measurements, providing reliable and

accurate readings on low turbidity. The HI 88703 meets and exceeds the requirements of USEPA

and Standard Methods.

The instrument is based on a state-of-the-art optical system which guarantees accurate results,

assures long term stability and minimizes stray light and color interferences. It also compensates for

variations in intensity of the lamp, making no need for frequent calibration.

The 25 mm round cuvets made from special optical glass guarantee the repeatability and consistency

of the measurements.

Turbidity measurements

can be made in the 0.00 to 4000 NTU (Nephelometric Turbidity Units)

range when ratiometric measurements are used and in the 0.00 to 40.0 NTU range when non ratio

method is used. The instrument has an EPA compliance reading mode which rounds the reading to

meet EPA reporting requirements. Alternative EBC and Nephelos measuring units are available.

Depending on the measured sample and needed accuracy, normal measurement, continuous

measurement or signal averaging measurement can be selected.

A two, three, four or five-point calibration could be performed by using the supplied (<0.1, 15,

100, 750 and 2000 NTU) standards. When user prepared standards are used, the calibration points

can be modified.
