Hanna Instruments HI88713-02 ISO 7027 Compliant Benchtop Turbidity Meter

The HI88713 Precision ISO Turbidity Benchtop Meter is designed for accurate turbidity measurement in water, even at very low levels. Its advanced optical system uses IR LED light and 25 mm round cuvettes to ensure high repeatability and minimize stray light or color interference. The meter supports multiple units (FNU, FAU, NTU, EBC) and measurement modes, with data logging and USB connectivity for easy storage. ISO 7027 compliance, GLP traceability, and tutorial/help modes make it ideal for laboratories monitoring drinking water, wastewater, and natural water sources.

  • Four Measurement Modes: FNU, FAU, NTU (ratio & non-ratio)
  • High Accuracy & ISO Compliant: Infrared LED minimizes color interference
  • GLP & Data Logging: Up to 200 records with calibration traceability
  • User-Friendly Interface: Backlit graphic LCD, contextual help, tutorial mode

Description

The HI88713 ISO Benchtop Turbidity Meter delivers precise and reliable measurements of water turbidity in accordance with ISO 7027 standards. Utilizing a state-of-the-art optical system with infrared LED, 25 mm round glass cuvettes, and a dual detector system, the meter compensates for variations in light source intensity and reduces stray light effects. It measures turbidity in multiple units, including FNU, FAU, NTU, and EBC, making it suitable for drinking water, wastewater, and natural water monitoring. Calibration can be performed using the supplied AMCO AEPA-1 primary standards, which are non-toxic, reusable, and NIST-traceable.

The instrument’s microprocessor automatically calculates turbidity values depending on the mode selected, correcting for color interferences and ratio/non-ratio measurements. The backlit graphic LCD provides clear and contextual guidance for calibration and measurement, while the tutorial mode ensures operators perform procedures correctly. With USB connectivity, data logging for 200 records, and GLP features, the HI88713 is a comprehensive turbidity solution for laboratories requiring accurate, repeatable, and traceable measurements.
