GENERAL DESCRIPTIONGENERAL DESCRIPTION

GENERAL DESCRIPTION

GENERAL DESCRIPTIONGENERAL DESCRIPTION

HI 8033, HI 8633, HI 8733, HI 8734 and HI 933000 are some of the most complete and versatile portable conductivity/TDS meters ever manufactured. Designed with utmost precision and simplicity, these meters provide for up to 3 or 4 measurement ranges. The conductivity of a solution depends on the temperature and for this reason measurements are carried out with reference to a standard temperature of 25°C. If the solution measured has a different temperature than 25°C, compensation must be performed.

HI 8033, HI 8633 and HI 8734 compensate for temperature manu- ally.

HI 8733 and HI 933000, with a built-in temperature sensor and circuitry, automatically compensate for temperature changes.

With HI 8733, the temperature coefficient is adjustable from 0 to

2.5% per degree Celsius depending on the type of solution tested. For all the other meters the temperature coefficient is fixed at 2%.

• Each meter is supplied complete with a 9V battery. Slide off the battery compartment cover on the back of the meter (see page 22). Install the battery while paying attention to its polarity.

• Connect the probe to the meter securely by aligning the pins with the socket and pushing the plug in.

With HI 933000, tighten the threaded ring.

• Make sure that the meter has been calibrated before taking any measurements (see page 11 for calibration procedure).

• Immerse the conductivity probe into the sample, with the holes on the shaft completely submerged.

If possible, use plastic beakers or containers to minimize any EMC interference.

• Tap the probe lightly on the bottom of the beaker to remove any air bubbles which may be trapped inside the PVC sleeve.

• Turn the instrument on by pressing the ON/OFF key or by setting the rotary switch (for HI 8033 only) to the desired mea-

The conductivity of an aqueous solution is the measure of its ability to carry an electrical current by means of ionic motion.

The conductivity invariably increases with increasing temperature. It is affected by the type and number of ions in the solution and by

the viscosity of the solution itself. Both parameters are temperature dependent. The dependency of conductivity on temperature is expressed as a relative change per degree Celsius at a particular temperature, commonly as percent per °C.

The TDS value in aqueous solutions is directly proportional to conductivity. The ratio between the two parameters depends on the solution and usually it is set to a factor of 0.5 (corresponding to a solution of CaCO

). This means that 1 µS/cm is equal to 0.5 mg/L (ppm) of TDS.

Highly acidic, alkaline samples or solutions with high salt content might have a different coefficient than the customary 2% per degree °C.

In order to calculate this coefficient follow the procedure below:

• Immerse the probe of HI 8733 in the sample and adjust the

TEMPERATURE COEFFICIENT knob to 0% (i.e. no compensation).

2.5

0.5

TEMPERATURE COEFFICIENT

• Condition the sample and probe to 25°C and note the conductivity reading, C

• Condition the sample and probe to a different temperature t°C (approximately 10°C different from 25°C) and note the conductivity reading C

• The temperature coefficient ß of the solution is calculated as given by the following formula:

ß = 100 x

(t - 25) x C

- C25)

The above procedure is suitable for determining the temperature coefficient in a laboratory or where the temperature of the solution can be controlled.

If this is not possible (e.g. on-site measurements), the following procedure can be used providing the sample temperature varies by at least 5°C or preferably 10°C:

• Immerse the probe of HI 8733 in the test solution and turn the TEMPERATURE COEFFICIENT knob to 0% (no compensation).

• Check the conductivity reading and record the value. Make sure the reading is stable, i.e. no greater variations than ±0.2 mS/ cm within a minute.

• Repeat the procedure when the temperature of the test solution has changed by at least 5°C. Wait for the conductivity reading to stabilize.

• Adjust the TEMPERATURE COEFFICIENT knob until the display shows the same value as recorded earlier.

• The value indicated by the knob is the temperature coefficient of the solution.

PROBE MAINTENANCEPROBE MAINTENANCE

PROBE MAINTENANCE

PROBE MAINTENANCEPROBE MAINTENANCE

Rinse the probe with tap water after every series of measurements. If a more thorough cleaning is required, remove the PVC sleeve and clean the probe with a cloth or a non-abrasive detergent. When reinserting the sleeve onto the probe, be sure that the sleeve is in the right direction with the four holes towards the cable end.

After cleaning the probe, recalibrate the instrument.

The probe body is in PVC. For this reason it must never come into close contact with a heat source. If the probe is exposed to high temperatures (above 50°C/122°F), the rings might become loose or detached, resulting in a serious impairment of the probe. In such cases, the probe has to be replaced.

When the battery becomes weak the meters will display "V" or an additional blinking decimal point (HI 8733).

When the low battery indicator appears, the battery has only a few hours left. A low battery will result in unreliable measurements.

It is recommended that the battery be replaced immediately. Battery replacement must only take place in a non-hazardous area

using an alkaline 9V battery. Slide off the battery compartment cover at the rear of the meter and

replace the 9V battery with a new one. Make sure the battery contacts are tight and secure before replacing the cover.
