5.1. GENERAL DESCRIPTION & INTENDED USE
The
HI97727
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
HI97727
meter measures color of water samples from 0 to 500 PCU. The method is
an adaptation of the Standard Methods for the Examination of Water and Wastewater,
18
th
Edition, Colorimetric Platinum Cobalt Method.
By comparison with known color of platinum cobalt, chloride standards method is
used to determine “apparent color” of water (color from suspended and dissolved
components measured using un-filtered samples) and “true color” (measured using
filtered samples after removal of slight turbidity).
The
HI97727
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
