CONDUCTIVITY MEASUREMENTS CONDUCTIVITY MEASUREMENTS CONDUCTIVITY MEASUREMENTS CONDUCTIVITY MEASUREMENTS CONDUCTIVITY MEASUREMENTS Make sure that the instrument has been calibrated before taking conductivity measurements (see page 8 for calibration procedure). Connect the probe to the back of the meter and switch the instrument on by pressing the ON/OFF key. - Page 7 FOR HI8820: • • • • • Immerse the probe in the solution submerging the holes of the sleeve (0.5 cm below). Tap the probe lightly on the bottom of the recipient to remove any air bubbles which may have being trapped inside the sleeve.

Page 8: Calibration
CALIBRATION CALIBRATION CALIBRATION CALIBRATION CALIBRATION INITIAL PREPARATION If you are measuring in the mS ranges, calibrate the meter using HI7030 (or HI8030) conductivity solution (12.88 mS @ 25°C) or HI7034 (or HI8034) conductivity solution (80 mS @ 25°C). Choose a solution with a conductivity value close to the solution to be measured. - Page 9 • Press the COND/TEMP key to display conduc- tivity readings and select the appropriate conductivity range e.g. "19.99 mS" for HI7030/HI8030, "99.9 mS" for HI7034/HI8034, "1999µS" for HI7031/HI8031, "199.9 µS" for HI7033/HI8033. • Using a small screwdriver adjust the trimmer on the rear panel until the display shows the conductivity reading at the tempera- ture of the solution noted earlier (see the conductivity vs.
- Page 10 • Press the COND/TEMP key to display conduc- tivity. • The display should read the conductivity of the calibrating solution at the reference tempera- ture. E.g. using HI7030/HI8030 with a so- lution at 18°C, the reading will be "12.88 mS". PROCEDURE FOR HI8820: •...
- Page 11 • Using a small screwdriver adjust the trimmer on the rear panel until the display shows the conductivity reading at 25°C (77°F), e.g.: "12.88 mS" for HI7030/HI8030, "80.00 mS" for HI7034/HI8034, "1413 µS" for HI7031/HI8031, "84 µS" for HI7033/HI8033.
