5.1. GENERAL DESCRIPTION & INTENDED USE
The HI97739 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.
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 HI97739 meter measures the fluoride content in water samples in the 0.0 to
20.0 mg/L (ppm). The method is an adaptation of the Standard Methods for the
Examination of Water and Wastewater, 18
th
Edition, SPADNS Method.
The HI97739 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
