• When the temperature is set manually,

"°C" symbol blinks. With the tempera-
ture probe connected, the "°C" symbol
is displayed continuously.

• Use the UP or DOWN arrow keys to

manually adjust the display reading
to the value of the reference ther-
mometer.

TAKING TEMPERATURE MEASUREMENTS (NOT FOR HI
8519)

• Taking a temperature measurement is very easy.
• Turn the instrument ON and press the RANGE key

(for

HI8520

and

HI8521

only) to get into tem-

perature mode.

• Make sure the temperature probe is connected

and allow the reading to stabilize (1 or 2 min-
utes).

• The temperature value will be dis-

played on the left LCD for

HI8417

.

TAKING ORP MEASUREMENTS

HI8417

,

HI8519

and

HI8521

have the capability to take ORP

measurements, using an ORP electrode. Hanna Instruments offers a
variety of ORP electrodes for this purpose (see page 35). Contact your
Dealer for more information.
Just as pH measurements allow the acidity or the alkalinity of a
substance to be expressed in numbers, oxidation-reduction potential
(redox) measurements provide the quantification of the oxidizing or
reducing power of any liquid.

For HI8519 only:

• Connect the ORP electrode to the meter and

submerge the tip (4 cm / 1½") into the sample
to be tested.

Note:

ORP measurements are taken without tem-
perature compensation.

• Press the mV key to enter the mV mode. Allow a few

minutes for the reading to stabilize.

• The display will indicate the absolute

mV value (positive or negative).
