PRELIMINARY EXAMINATION

HI 2314 and HI 2315 are bench top multi-range conductivity meters for
the laboratory.

Four measurement ranges ensure the highest resolution and precision for
your measuring requirements.

Single point calibration is performed manually simply by adjusting a
knob on the front of the meter.

Temperature compensation of the readings is automatic for the HI 2315
and HI 23151 models, thanks to the temperature sensor incorporated in
probe, with userselectable temperature coefficient.

With HI 2314 the temperature compensation is manual and the tempe­rature value can be also set with a knob.

The rugged probe with platinum 4-ring sensor responds faster than
conventional stainless steel models and can be also used for measuring
highly acidic or alkaline samples, or at high temperature.

In addition, the HI 23151 model offers analog output of 0 to 5V that
represents the full conductivity scale across all 4 ranges.

GENERAL DESCRIPTION

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 damage, notify your dealer.

Each meter is supplied complete with:

• 4-ring conductivity probe with 1 m (3.3’) cable

• HI 76300 for HI 2314

• HI 76303 for HI 2315 and HI 23151

• 12 Vdc adapter

• Instruction manual

Note: Save all packing material until you are sure that the instrument

functions correctly. All defective items must be returned in the
original packing with the supplied accessories.
