Specification of Turbidity Meter Hanna HI 98703
HI98703Turbidity Meter Fast Tracker™ Technology, EPA Compliant
The HI98703 Precision Turbidity Portable Meter is specially
designed for water quality measurements, providing reliable and accurate
readings, especially in the low turbidity range. The instrument is based
on a state-of-the-art optical system which guarantees accurate results,
assures long term stability, and minimizes stray light and color interferences.
Periodic calibration with the supplied standards compensates for any variations in intensity of the tungsten
lamp. The 25 mm round cuvettes composed of special optical glass guarantee the
repeatability of turbidity measurements.
EPA Compliant Measurement
The HI98703 meets and exceeds the requirements of EPA and
Standard Methods for turbidity measurements. When the meter is in EPA mode all turbidity readings
are rounded accordingly to meet reporting requirements.
Backlit Display
A backlit LCD display provides
an easy to understand, user-friendly interface.
Displayed codes guide the user step-by-step through routine operation and
calibration.
Multiple reading modes
Normal, continuous, or signal averaging measurement are
reading modes available.
Calibration
A two, three, or four-point turbidity calibration can
be performed by
using the supplied (<0.1, 15, 100, and 750 NTU) standards.
Calibration points can be modified if user-prepared standards are used.
AMCO AEPA-1 Primary Turbidity Standard
The AMCO AEPA-1 supplied standards are recognized as a
primary standard by the USEPA. These non-toxic standards are made of styrene
divinylbenzene polymer spheres that are uniform in size and density. The
standards are reusable and stable with a long shelf life.
GLP Data
The HI98703 features complete GLP (Good Laboratory Practice)
functions that allow traceability of the calibration conditions. Data includes
calibration points, date, and time.
Data Logging
Up to 200 measurements can be stored in the internal memory
and recalled at any time.
Data Transfer
For further storage or analysis options, logged data can be
downloaded to a Windows compatible PC using the RS232 or USB port and the
HI92000 software.
