Hanna Instruments hi 98106 User Manual

Champ is a rugged pH tester with replaceable
electrode and renewable reference junction. The
instrument can be calibrated at one point by the
user, simply acting on the calibration trimmer.

CONDITIONING:

CONDITIONING:
• Remove the cap.
• To activate the electrode, immerse

the

Champ

in HI70300 storage

solution for 2 hours.

CALIBRATION:

CALIBRATION:
• Immerse the

Champ

in pH

7.01 (HI7007) buffer solution.

• Allow the reading to stabilize

and with a small screwdriver
turn the Calibration Trimmer
until the display shows "7.0"

The calibration is now complete.
Note

Note

Note: the calibration can be performed

at pH 4.0, pH 7.0 or pH 10.0,
according to the different applications.

OPERATION:

OPERATION:
• Remove the protective cap.
• Turn the

Champ

on with the ON/

OFF switch located on the top of the
meter.

• Immerse it in the solution to be

tested without exceeding the maxi-
mum immersion level.

• Stir gently and wait for the reading

to stabilize.

• After use, rinse the electrode with water to

minimize contamination.

• Store the electrode with a few

drops of storage (HI70300) or
pH7 (HI7007) solution in the
protective cap.

• Always replace the protective cap after use.

DO NOT USE DISTILLED OR DEIONIZED WATER

FOR STORAGE PURPOSES.

• Large differences in pH readings (±1 pH) could

be due to lack of calibration or dry electrode.

MAINTENANCE:

MAINTENANCE:
The sensor should be kept moist at all times. For this
purpose, always keep wet the tissue inside the
protective cap. In case of erroneous readings even
after an accurate conditioning and calibration, the
reference junction might be contaminated or clogged.

Pull out 2 mm (1/8'') of
the cloth junction to renew
the electrode reference (it is
recommended to cut the cloth
leaving always at least 2
mm -1/8'' over the refer-
ence compartment) and re-
peat the calibration proce-
dure.
The cloth junction can be pulled out approximately
20 times. After that, the electrode can be replaced
(see the Electrode Replacement section).

BATTERY REPLACEMENT:

BATTERY REPLACEMENT:
When display fades the batteries must be replaced.
Slide off the battery compartment cover and replace
all four 1.5V batteries while paying attention to
their polarity.

Batteries should only be replaced in a nonhazardous
area using the battery type specified in this instruction
manual.
