5.1. GENERAL DESCRIPTION AND INTENDED USE
The
HI97728
is an auto-diagnostic portable meter 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’s CAL Check
cuvettes are made with NIST traceable standards.
The built-in tutorial mode guides the users step-by-step through the measurement
process. It includes all steps required for sample preparation, the required reagents
and quantities.
The
HI97728
meter measures the nitrate content in water samples in the 0.0 to 30.0
mg/L (ppm) as NO
3
-N range. The method is an adaptation of the Cadmium Reduction
method.
The
HI97728
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
