The HI-97752 is an auto-diagnostic portable photometer that benefits from Hanna’s years of experience as a manufacturer of analytical instruments. It has an advanced optical system that uses a Light Emitting Diode (LED) and a narrow band interference filter that allows for accurate and repeatable readings.

Hanna's extended description

Each photometer is delivered in a cardboard box and is supplied with:

  • Sample cuvette (2 pcs.)
  • Sample cuvette cap (2 pcs.)
  • Plastic stopper (2 pcs.)
  • 1.5V AA Alkaline batteries
  • Instrument quality certificate
  • Instruction manual

  • The optical system is sealed from outside dust, dirt and water. The meter uses an exclusive positive-locking system to ensure that the cuvettes are placed into the holder in the same position every time.

    With the CAL Check™ functionality, users are able to validate the performance of the instrument at any time and apply a user calibration (if necessary). Hanna Instruments CAL Check cuvettes are made with NIST traceable standards.

    The built-in tutorial mode guides users step-by-step through the measurement process. It includes all steps required for sample preparation, the required reagents and quantities.


    The HI-97752 meter measures two important parameters in:

  • drinking water
  • surface water
  • ground water
  • wastewater
  • swimming pools

  • Calcium is a vital plant nutrient and helps to strengthen plant cell walls protecting against heat stress. The method for calcium is an adaptation of the Oxalate Method.

    Magnesium is an essential nutrient and helps build a strong immune system. The method for magnesium is an adaptation of the Calmagite Method.

    The HI-97752 photometer is a compact and versatile meter suitable for field or bench measurements, featuring a:

  • Sophisticated optical system
  • Meter validation using certified CAL Check cuvettes
  • Tutorial mode guides the user step-by-step
  • Auto logging
  • Waterproof IP67, floating case
  • GLP features
  • Specifications
