Hanna Instruments HI 8014, Instruction Manual

23

22

To measure the mV of a sample submerge
the ORP electrode tip (4 cm/1½") into the
sample to be tested.
Allow a few minutes for the readings to
stabilize. Also, see page 42 for more informa-
tion about REDOX measurements.

Note (for HI 8424 and HI 9622 only):

 the

resolution is 0.1 mV for values within ±400mV
range.

TAKING  TEMPERATURE  MEASUREMENTS  (EXCEPT
FOR HI 8014)

Turn the instrument ON and press °C (

HI 8314  and  HI 8915)  or

RANGE 

(

HI 8424

 and 

HI 9622

).

Make sure the temperature probe (for 

HI 8314

,

HI 8915

, 

HI 8424 

and 

HI 9622

) or pH/°C

electrode (for 

HI 9214 

and 

HI 931000

) is con-

nected to the meter.
Dip the liquid/general purpose temperature
probe or the pH/°C electrode into the sample
and allow the reading to stabilize (a couple of
minutes).
For 

HI 9214

 only: to display the measured temperature, press and

hold the °C button on the top of the meter. When the button is
released, the display will return to the pH reading.

For 

HI 931000

 only: to display the measured

temperature, press and hold the °C key. When
the key is released, the display will return to
the pH reading.

compensate for it (HI 8424 and HI 9622 only). In this case, the
temperature probe must be disconnected.
With 

HI 8314

 and 

HI 8915 

when the temperature probe is discon-

nected, the pH reading will be compensated at a fixed 25°C
temperature. If a different compensation is required, reattach the
temperature probe.

SETTING  THE  TEMPERATURE  FOR  MANUAL
COMPENSATION (HI 8424 AND HI 9622 ONLY)

If the temperature probe is defective or if
temperature is to be set manually, 

unplug

the temperature probe

 and record the tem-

perature of the sample with a ChecktempC or
an accurate thermometer.
• Press RANGE to select the temperature

measurement mode. The "°C" symbol will
blink to indicate that the temperature
probe is not connected.

• Press the UP and DOWN arrow keys to display the sample

temperature (e.g. 25°C).

• Press RANGE to select the pH measurement mode and immerse

the pH electrode into the solution. The displayed pH reading will
be temperature compensated.

ORP  MEASUREMENTS  (HI 8014,  HI 8314,  HI 8424,
HI 8915 AND HI 9622 ONLY)

Connect the ORP electrode to the BNC socket on the top of the meter.
To enter the "mV" mode (ORP Oxidation Re-
duction Potential) turn the instrument ON and
select the mV mode (

HI 8014, HI 8314 and

HI 8915  only

) or press the RANGE key until

the display changes to mV (

HI 8424  and

HI 9622 only

).
