Portable turbidity meter HI-98713

for drinking water

HI 98713 is a high accuracy ISO compliant portable turbidimeter that benefits from HANNA’s years of experience as manufacturer of analytical instruments. The HI 98713 meets and exceeds the requirements of the ISO 7027 for water quality. The instrument is specially designed for water quality measurements, providing a reliable and accurate reading on low turbidity values. The HI 98713 instrument measures the turbidity of a sample in the 0.00 to 1000 FTU (Formazin Turbidity Units) range. An effective algorithm calculates and converts the detectors output in FTU. Depending on the measured probe and needed accuracy, normal measurement, continuous measurement, or signal averaging measurement can be selected. The instrument is based on a state-of-the-art optical system, which guarantees accurate results. The optical system, consisting in an infrared LED and two detectors (scattered and transmitted light), assures long term stability and minimizes stray light and color interferences. It also compensates for variations in intensity of the LED, minimizing the need of frequent calibration. The 25 mm round cuvets made from special optical glass guarantee the repeatability and consistency of the measurements.
