GENERAL DESCRIPTION
The Hanna C114 is a portable microproces­sor driven, multiparameter instrument. The meter measures Free & Total Chlorine 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. C114 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.
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 chlorine parameters, all the operator has to do is zero the blank sample and then add 1 packet of reagent. 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.
C114 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.
There are eight keys for the different opera­tional modes. The large Liquid Crystal Dis­play is dual-level: the upper level has four

PRINCIPLE OF OPERATION
Turbidity Mode
C 114 has been designed to perform mea-
surements according to the USEPAs 180.1 method and the Standard Method 2130B.
The instrument functions by passing a beam of light through a vial containing the sample being measured.
The light source is a Pure Green LED to ensure that any interference caused by a colored samples is minimized.
A sensor, positioned at 90° with respect to the direction of light, detects the amount of light scattered by the undissolved particles present in the sample. The microprocessor converts such readings into NTU* values.
Colorimetric Mode
The color of every object we see is deter­mined by a process of absorption and emis­sion of the electromagnetic radiation (light) of its molecules.
Colorimetric analysis is based on the principle that specific compounds react with others to form a color, the intensity of which is proportional to the concentration of the substance being measured.

LIGHT
DETECTOR
When a substance is exposed to a beam of light intensity Io, a portion of the radiation is absorbed by the substance's molecules and a radiation of intensity I, lower than Io, is emitted.
The quantity of radiation absorbed is given by the Lambert-Beer Law:
log Io/I = ελ c d
NTU units are equal to FTU units. However, there are other known measurement units for turbidity, namely the Jackson Turbidity Unit (JTU) based on the old method of Jackson's candle, and Silica Unit (mg / L of SiO2). The conversion table between these measurement units is shown below:
JTU NTU/FTU SiO2 (mg/L)
JTU 1 19 2.5
NTU/FTU 0.053 1 0.13
SiO2 (mg/L) 0.4 7.5 1
6
* 1 NTU = 1 FTU
Where log Io/I = Absorbance (A)
ελ= molar extinction coefficient of the
substance at wavelength λ
c = molar concentration of the
substance
d = optical distance light travels
through the sample
Since other factors are known, the concen­tration "c" can be calculated from the color intensity of the substance determined by the emitted radiation I.
An LED (Light Emitting Diode) emits radiation at a relatively narrow spectrum, supplying the system with the intensity Io.
7
A substance absorbs a color complimentary to the color it emits. For example, a substance appears yellow because it absorbs blue light. As a result, the Hanna meters use LEDs with specific wavelengths to measure samples.
The optical distance (d) is measured by the internal diameter of the cuvet containing the sample.
The photoelectric cell collects the radiation I that is not absorbed by the sample and converts it into an electric current.
The microprocessor converts the value into the desired measuring unit and displays it on the LCD.
The measurement process is done in two phases: setting the meter to zero and actual measurement.
The cuvet is an optical element and hence has an important role in the measurement process. Both the measurement and the calibration cuvets must be optically identical to provide the same measurement conditions.
It is also important that the surface of the cuvet is clean and free from scratches or dents, in order to avoid measurement interference due to unwanted reflection and absorption of light.
It is recommended that wherever possible the cuvet walls are not touched by the operator.
Furthermore, in order to maintain the same conditions during the zeroing and the measuring phases, it is necessary to close the cuvets to prevent any contamination.

FUNCTIONAL DESCRIPTION
1) Primary LCD: The four-digit LCD shows all
segments for several seconds when the meter is switched on. It then displays four dashes to indicate ready to measure. It is also the area where the date, time and value of last calibration are shown. In Read and Zero mode,
SIP is shown to indicateSample In Progress. The
upper level also indicates the concentration or turbidity of the sample, as well as differ-
9
ent diagnostic modes, such as -BA- for low battery.
2) Secondary LCD: The three-digit LCD shows the
current mode of measurement that is F CL, tCL”, “tr”, and diagnostic or calibration modes, such as “d11”, 2 Fn, 5c1”.
3) DATE: Indicates that the upper level
of LCD is showing the cur­rent date, the date of last cali­bration or the date of logged measurement in memory.
4) TIME: Indicates that the upper level
of LCD is showing the cur­rent time, the time of last cali­bration or the time of logged measurement in memory.
5) LOBAT: Blinking segment warns user
of low battery voltage.
