PRELIMINARY EXAMINATION
Remove the instrument from the packing
material and examine it carefully to make
sure that no damage has occurred during
shipping. If there is any noticeable damage,
notify your Dealer.
Note: Save all packing materials until you
are sure that the instrument functions
correctly. All defective items must be
returned in the original packing materials
together with the supplied accessories.
GENERAL DESCRIPTION
HI 8510, HI 8512, HI 8710, HI 8711, HI 8720,
HI 931500, HI931501 and HI 932500 are pH-
ORP panel-mounted indicators and controllers designed for simplicity of use in a wide
range of industrial process applications.
The models are designed with DIN standard
panel mount with membrane keypads on the
front panel, a large LCD display and
autodiagnostic functions (not HI 931500,
HI 931501 and HI 932500).
Connections to the power supply, contacts
and recorders are made through screw terminals on the rear panel.
Two models are available for HI 8510, HI8711,
HI 8512, HI 8520. The E-model accepts input
direct from the pH or ORP electrode, while
the T-model accepts a 2-wire current loop of
4 to 20mA from a pH or ORP transmitter.
HI 931500, HI 931501 and HI 932500 are
equipped with a BNC socket to connect a
pH-ORP electrode.
Other features include: recorder output in 0
to 20mA or 4 to 20 mA; LED indicators
which identify the controller mode.
3
Using the pH indicators in conjunction with a
4-20mA output pH transmitter HI 8614 or
HI 8614L (with LCD display) and using the
ORP indicators in conjunction with a 4-20 mA
output ORP transmitter HI 8615 or HI 8615L
(with LCD display) will assure you of a strong,
interference-free signal at distances up to
300 m (1000 ft).
All instruments are supplied with a plastic
transparent front cover and mounting brackets (electrode and mains cable excluded).

MECHANICAL DIMENSIONS
The meters have a DIN 43 700 casing in
black anodized aluminum. Front and back of
the instruments are supplied with shockproof
ABS plastic and a transparent protective cover
for the front panel.

LOCATION
BRACKET
Adjustable location brackets (supplied with
the meter) allow the indicator to slide into the
cutout and will hold the unit securely in place.
190 mm (7.50") is the minimum amount of
room required to install the indicator with the
cables connected.
