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,

immediately notify your dealer.

Each model is supplied complete with

transparent splash-proof front cover, mounting

brackets and instruction manual

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 and HI8512 pH and ORP panel-

mounted indicators, and HI 8710, HI 8711

and HI 8720 pH and ORP controllers, are

ideal for process control monitoring in a wide

range of industrial applications.

These instruments have been designed for

easy and fast installation, and are provided

with membrane keypads on the front panel,

large display and autodiagnostic functions.

All connections are made through screw ter-

minals on the rear panel.

Two versions are available for each model, to

accept either a direct input from a pH or ORP

electrode (E version) or from a transmitter

through 4-20mA input (T version).

Moreover, you can choose the output

configuration for connecting a recorder or a

PLC, between 0-20 or 4-20 mA.

DearCustomer,

ThankyouforchoosingaHANNAinstruments®

product.

Please read this instruction manual carefully

beforeusingtheinstrument.

If you need additional technical information,

do not hesitate to e-mail us at

[email protected].

These instruments are in compliance with the

directives.

MECHANICAL DIMENSIONS

The meters are provided with a black anodized

aluminum body, front and back panels in

shockproof ABS plastic and a transparent

splash-proof front cover.

Front view of the panel-mounted unit

The dimensions show the cutout size for the

installation.

Side view of the panel-mounted unit

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 space re-

quired to install the indicator with complete

wiring.
