GENERAL DESCRIPTION
The HI 95747 is an auto diagnostic portable microprocessor meter that benefits from Hanna’s
years of experience as a manufacturer of analytical instruments. It has the advanced optical
system based on a special tungsten lamp and a narrow band interference filter that allows most
accurate and repeatable readings. All instruments are factory calibrated and the electronic and
optical design minimizes the need of frequent calibration.
With the powerful CAL CHECKTM validation function you are able to validate good performance
of your instrument at any time. The validation procedure is extremely user friendly. Just use the
exclusive Hanna ready-made, NIST traceable standards to verify the performance of the
instrument and recalibrate if necessary.
All instruments are splash proof and the lamp and filter units are protected from dust or dirt by
a transparent cup. This makes the instruments fulfill field applications. Display codes aid the
user in routine operation. The meter has an auto-shut off feature that will turn off the instrument
after 10 minutes of non use or after 1 hour if left in the
The meter uses an exclusive positive-locking system to ensure that the cuvet is in the same
position every time it is placed into the measurement cell. It is designed to fit a cuvet with a
larger neck making it easier to add both sample and reagents. The cuvet is made from special
optical glass to obtain best results.
The HI 95747 meter measures the free dissolved
0.000 to 1.500 mg/L (ppm) range. The method is an adaptation of the USEPA approved
bicinchoninate method.

PRECISION AND ACCURACY
Precision is how closely repeated measurements
agree with each other. Precision is usually expressed
as standard deviation (SD).
Accuracy is defined as the nearness of a test result to
the true value.
Although good precision suggests good accuracy,
precise results can be inaccurate. The figure explains
these definitions.
In a laboratory using a standard solution of 0.750
mg/L Copper and a representative lot of reagent, an
operator obtained with a single instrument a standard
deviation of 0.015 mg/L.

PRINCIPLE OF OPERATION
Absorption of Light is a typical phenomenon of interaction between electromagnetic radiation and
matter. When a light beam crosses a substance, some of the radiation may be absorbed by
atoms, molecules or crystal lattices.
If pure absorption occurs, the fraction of light absorbed depends both on the optical path length
through the matter and on the
Lambert-Beer Law:
Where:
-log I/I
= Absorbance (A)
o
Io= intensity of incident light beam
I = intensity of light beam after absorption
ε
= molar extinction coefficient at wavelength λ
λ
c = molar concentration of the substance
d = optical path through the substance
Therefore, the concentration "c" can be calculated from the absorbance of the substance as the
other factors are known.
Photometric chemical analysis is based on the possibility to develop an absorbing compound
from a specific chemical reaction between sample and reagents. Given that the absorption of a
compound strictly depends on the wavelength of the incident light beam, a narrow spectral
bandwidth should be selected as well as a proper central wavelength to optimize measurements.
The optical system of Hanna's HI 95 series colorimeters is based on special subminiature
tungsten lamps and narrow-band interference filters to guarantee both high performance and
reliable results.
