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 HI 83000 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 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 physicochemical characteristics of substance according to the Lambert-Beer Law:

	-log	λ c d
		ε
	/ I
		o
		or
	A	ελ c d
Where:
-log	= Absorbance (A)
I/
o
	= intensity of incident light beam
I
o
	= intensity of light beam after absorption
I
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.

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 83000 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.

HI 83000 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 band-

width, to obtain a light beam of intensity	or
	Io .
The photoelectric cell collects the radiation	that is not absorbed by
	I

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 identical 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.

BATTERY REPLACEMENT

Besides to the 12 VDC supply, this meter can also be fed by two 9V batteries.

To prolong battery life, switch your meter off after use. However, the meter has an auto-shut off feature that will turn itself off after 10 minutes of non-use.

A blinking "LOBAT" on the display, while a measurement is in progress, indicates low voltage and the batteries should be replaced.

If the batteries are not replaced immediately, in order to prevent erroneous readings due to low voltage, "-BA-" is displayed soon afterwards. At this point the batteries must

be changed.

Battery replacement must only take place in a non-hazardous area using two 9V alkaline batteries.

Remove the battery cover on the back of	attach two fresh
9V batteries, while paying attention to the correct polarity, and
replace the cover.

The meter will turn on automatically when a new battery is connected.

Note: Windows Terminal® and all the other terminal programs that support the ANSI escape sequence, represent the DLE character by the string ‘^P’ and the CR character by the string ‘^M’.

GUIDE TO DISPLAY CODES

Note: The secondary LCD below shows a generic "P– –", whereas the meter will indicate the exact program number (e.g. "P1" for Ammonia LR).

This indicates that the meter is in a ready state and zeroing can be performed.

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 instrument is performing an internal check-up.

The blinking "LOBAT" indicates that the battery voltage is getting low and the batteries need to be replaced.

This indicates that the batteries are dead and must be replaced.

Light over range. The cuvet is not inserted correctly and an eccess ambient light is reachingthedetector.Ifthecuvet isproperly inserted, then contact your dealer or the nearest Hanna Customer Service Center.

The lamp is not working properly. Contact your dealer or the nearest Hanna Customer Service Center.

This indicates that the meter has lost its configuration. Contact your dealer or the nearest Hanna Customer Service Center.

ERROR MESSAGES a) on zero reading:

This indicates that the zeroing procedure failed due to a low signal-to-noise ratio. In this case press ZERO again.

The instrument cannot adjust the light level. Please check that the sample does not contain any debris.

There is not enough light to perform a measurement. Please check the preparation of the zero cuvet.

There is too much light to perform a measurement. Please check the preparation of the zero cuvet.

POTASSIUM ULTRA HIGH RANGE

For samples containing more than 200 ppm of Potassium: first follow the sample preparation procedure described at page 19 for NUTRIENTS SOLUTION (HR). Then add to the graduated cylinder 20 mL of the prepared sample (for HR) and fill the cylinder with demineralized water from the Demineralizer Bottle up to the 100 mL mark.

Follow the MEASUREMENT PROCEDURE at page 43.

Read the result in mg/L of Potassium on the display and multiply the reading by 5 to obtain the real concentration of Potassium in your sample.

INTERFACE WITH PC

To connect your meter to the PC use the optional HI 920010 (available from your Hanna Dealer). Make sure that your meter is switched off and plug the connectors, one into the meter RS 232C socket, the other into the serial port of your PC.

Note: Cables other than HI 920010 may use a different configuration, in which case, communication between the meter and the PC may not be possible.

SETTING THE BAUD RATE

The transmission speed (baud rate) of the meter and the external device must be identical. The meter is factory set to 2400.

If you wish to change this value, please contact your nearest Hanna Center.

SENDING COMMANDS FROM PC

With terminal programs such as, for example, Telix®, Windows Terminal®, it is possible to remotely control your Hanna Instruments bench meter. Use HI 920010 cable to connect the meter to the PC, start the terminal program and set the communication options as follows: 8, N, 1, no flow control.

Command Types

To send a command to the pH meter the scheme is:

This line makes the computer send a Data Link Escape character (/ or ?), the command expressed as a number or a 3-character sequence and a CR character.
