User Guide

For best results in calibrating your meter, choose a conductivity/TDS

solution that is closest in value to the sample to be measured.

For example if your measurements are in the 2 to 20 mS/cm range,

ideally use the HI 7030 or HI 8030 (12880 µS/cm=12.88 mS/cm)

conductivity calibration solution.

For accurate calibration, use

two beakers for each solution:

the first one for rinsing the

probe and the second one for

calibration. In this way, contamination of the calibration solutions is

minimized.

In order to minimize any EMC interference, use plastic beakers for the

solutions, wherever possible.

A complete list of the Hanna calibration solutions is given in the

Accessories section (page 32).

PROCEDURE FOR HI 9033 AND HI 9130

• Fill a beaker with 8 cm (3¼") of conduc-

tivity calibration solution (if possible fill

two beakers and use one as rinse and

the other for calibration).

• Make sure that the probe is connected to

the meter securely by aligning the pins

with the socket, pushing the plug in

and tightening the threaded ring.

• Immerse the probe into the beaker. The

level of solution must be higher than the

holes on the PVC sleeve.

• Turn the instrument on by pressing the ON/OFF key and select

the appropriate range (e.g. 19.99 mS/cm).

• Tap the probe repeatedly on the bottom of the beaker and stir it

to ensure that no air bubbles are trapped inside the sleeve.

• If the temperature of the probe is close to that of the solution, the

display will stabilize quickly and provide you with temperature

compensated conductivity measurements. However, allow a few
