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 terminals 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.
