PRELIMINARY EXAMINATION
Remove the instrument from the packing
material and examine it carefully to make
sure that no damage has occurred during

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, HI 931501 and HI 932500 are pH-
ORP panel-mounted indicators and control-
lers designed for simplicity of use in a wide
range of industrial process instrumentation.
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 termi-
nals on the rear panel.
Two models are available for HI 8510, HI 8711,
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 20 mA 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 20 mA or 4 to 20 mA; LED indicators
which identify the controller mode.
