5.1. GENERAL DESCRIPTION & INTENDED USE
The
HI97736
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
HI97736
meter measures the total hardness content in water samples from 0.00
to 4.70 mg/L (ppm) and the pH in water samples from 6.5 to 8.5 pH. The method for
total hardness is an adaptation of the Standard Methods for the Examination of Water
and Wastewater, 18
th
Edition, Colorimetric Method. The reaction between magnesium
and calcium hardness and reagents causes a violet tint in the sample.
The method for pH is an adaptation of Phenol Red Method.
The
HI97736
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
