GENERAL DESCRIPTIONGENERAL DESCRIPTION

GENERAL DESCRIPTION

C 99 & C 200 Series is a line of 15 different bench, microprocessor-

based photometers that measure up to 46 parameters in water and

wastewater. These multipurpose meters are manufactured to measure

the most important parameters of the application they have been

especially designed for:

C 99 Laboratories, with COD C 200 Laboratories

C 203 Aquaculture C 205 Boilers & Cooling Towers

C 206 Environmental Testing C 207 Industrial Wastewater

C 208 Water Conditioning C 209 Education

C 210 Pulp & Paper Mills C 211 Chemical Manufacturers

C 212 Power Plant Utilities C 213 Municipal Wastewater

C 215 Nutrient Analyses C 216 Swimming Pool Applic.

C 218 Environmental Applic.

All meters use an exclusive positive-locking system to ensure that the cuvet

is in the same position every time it is placed into the measurement cell.

The reagents are in liquid or powder form and are supplied in bottles

or in packets. The amount of reagent is precisely dosed to ensure the

maximum repeatability.

Display codes aid the user in routine operations.

The meters have an auto-shut off feature, turning the unit off after

10 minutes of non-use.

The C 99 & C 200 Series can be connected to a personal computer via

the HI 920010 three wire RS 232 cable. The HI 92000 Hanna

Windows®Compatible Software aids the user to manage all test

data.

PRINCIPLE OF OPERATIONPRINCIPLE OF OPERATION

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 physico-

chemical characteristics of substance according to the Lambert-Beer

Law:

-log I/Io= ελc d

A = ελc d

Where:

-log I/Io=Absorbance (A)

Io=intensity of incident light beam

I=intensity of light beam after absorption

ελ=molar extinction coefficient at wavelength 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.

SPECIFICATIONSSPECIFICATIONS

SPECIFICATIONS

The optical system of Hanna's C 99 & C 200 multiparameter

photometers is based on special subminiature tungsten lamps and

narrow-band interference filters to guarantee both high performance

and reliable results.

Four measuring channels (at four different wavelengths) allow a wide

range of tests.

C 200 Block diagram (optical layout)

A microprocessor controlled special tungsten lamp emits radiation

which is first optically conditioned and beamed to the sample

contained in the cuvet. The optical path is fixed by the diameter of

the cuvet. Then the light is spectrally filtered to a narrow spectral

bandwidth, to obtain a light beam of intensity Ioor I.

The photoelectric cell collects the radiation Ithat is not absorbed by

the sample and converts it into an electric current, producing a

potential in the mV range.

The microprocessor uses this potential to convert the incoming value

into the desired measuring unit and to display it on the LCD.

The measurement process is carried out in two phases: first the meter

is zeroed and then the actual measurement is performed.

The cuvet has a very important role because it is an optical element

and thus requires particular attention. It is important that both the

measurement and the calibration (zeroing) cuvets are optically iden-

tical to provide the same measurement conditions. Whenever possible

use the same cuvet for both.

It is also necessary that the surface of the cuvet is clean and not

scratched. This is to avoid measurement interference due to unwanted

reflection and absorption of light. It is recommended not to touch the

cuvet walls with hands.

Furthermore, in order to maintain the same conditions during the

zeroing and the measuring phases, it is necessary to close the cuvet

to prevent any contamination.

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.

Note: The secondary LCD below shows a generic "P– –", whereas the

meter will indicate the exact program number (e.g. in C 200,

"P1" for Aluminum).

Sampling in progress. This flashing

prompt appears each time the meter is

performing a measurement.

The microprocessor is adjusting the light

level, indicated by a scrolling "SIP".

This indicates that the meter is in a zeroed

state and measurement can be performed.

The blinking "LOBAT" indicates that the

battery voltage is getting low and the

batteries need to be replaced.

The light level is accepted. The instrument

is ready to perform a zero reading. This

flashing prompt will only appear when a

secondzeroreadingneedsto beperformed.

Follow the measurement procedure de-

scribed in the related chapter.

The instrument is performing an internal

check-up.

This indicates that the meter is in a ready

state and zeroing can be performed.

This indicates that the batteries are dead

and must be replaced.

This indicates that the meter has lost its

configuration. Contact your dealer or the

nearest Hanna Customer Service Center.

make sure that you use the same cuvet for

reference (zero) and measurement.

1) A flashing value of the maximum

concentration indicates an over range

condition.Theconcentrationofthesample

is beyond the programmed range: dilute

the sample and rerun the test.

2) A flashing value lower than the

accuracy of the result is not guaranteed.

Repeat the reading procedure.

The sample and zero cuvet are inverted.

TIPS FOR AN ACCURATE MEASUREMENTTIPS FOR AN ACCURATE MEASUREMENT

TIPS FOR AN ACCURATE MEASUREMENT

The instructions listed below should be carefully followed during

testing to ensure best accuracy.

• Color or suspended matter in large amounts may cause interfer-

ence, therefore, these should be removed by treatment with active

carbon and by prior filtration.

• For a correct filling of the cuvet: the

liquid in the cuvet forms a convexity

on the top; the bottom of this convex-

ity must be at the same level of the

10 mL mark.

• In order to measure exactly e.g. 0.5 mL of sample or reagent

with the 1 mL syringe, push the plunger completely into the

syringe and insert the tip into the solution. Pull the plunger up

to above the 0.0 mL mark. Take out the syringe and clean the

outside of the syringe tip. Then, adjust the plunger to the 0.0 mL

mark (the lower edge of the seal must be exactly on the 0.0 mL

mark). Be sure that no drops are hanging on the tip of the

syringe, if so eliminate them. Then, keeping the syringe in vertical

position above the cuvet, push the plunger down until the lower

edge of the seal is exactly on the 0.5 mL mark. Now the exact

amount of 0.5 mL has been added to the cuvet, even if the tip

still contains some reagent or sample.

10 mL

• Proper use of the dropper: to get good

reproducible results, tap the dropper on the

table for several times and wipe the outside

of the dropper tip with a cloth. Always keep

the dropper bottle in a vertical position

while dosing the reagent.
