The Hanna C 102 is a portable microprocessor driven, multiparameter, turbidity and ion
specific meter. It measures Free & Total Chlorine, Cyanuric Acid, pH, Iodine, Bromine, Low
Range Iron and Turbidity.
In the colorimetric mode, the user can select
either factory preprogrammed calibration settings or calibrate the meter using customized
calibration values based on the concentration
or relative absorbance of the sample. Calibration data is also stored in a non-volatile
EEPROM.
In the turbidity mode, periodic recalibration of
the meter with primary standards according
to regulatory requirements or personal experience is suggested. Turbidity ranges are 0.00-
9.99 NTU and 10.0-50.0 NTU.
C 102 complies with G.L.P. Standards (Good
Laboratory Practice), that is:
• When switched on, the LCD displays all
segments (display check).
• Battery status is monitored during every
measurement cycle warning the user if the
batteries become weak. In addition, C102
will turn itself off before low voltage causes
erroneous readings.
• It utilizes a real time clock and recalls
calibration data such as date, time and
calibration values.
There are eight keys for the different
operationals modes. The large Liquid Crystal
Display is dual-level: the upper level has four
digits and can display the measured parameter in hundredths. The lower level has three
characters and indicates current mode (e.g.
F CL for free chlorine or TR for turbidity).
Different LCD segments indicate low battery,
logging mode, date, time, etc.
A pure Green LED has been utilized as a
light source for both turbidimetric and colorimetric measurements. A silicon photocell is
used to receive transmitted light from colorimetric channel while another photocell receives scattered light from the turbidimetric
(nephelometric) channel.
In order to measure colorimetric parameters,
all the operator has to do is zero the blank
sample and then add 1 packet of reagent (for
Bromine, Chlorine, Cyanuric Acid, Iodine and
Low Range Iron) or 0.2 mL of Phenol Red (for
pH). After placing the cuvet back in the meter
and pressing READ, the measurements are
shown directly on the LCD.
The instrument operates with four AA batteries and may be operator-programmed to turn
itself off automatically after 10, 20, 30, 40, 50
or 60 minutes of inactivity.
C 102 and all accessories such as sample
vials, reagent pillows, primary standards, can
be easily stored in the optional carrying case
(HI 710031).
To facilitate field tests, the meter provides a
logging mode. In this mode, the user can
store up to twenty five time-tagged measurements in RAM and scroll the memory at any
time.
