WARRANTY

All Hanna Instruments meters are warranted for two years against
defects in workmanship and materials when used for their intended
purpose and maintained according to instructions. Electrodes and
probes are warranted for a period of six months.
This warranty is limited to repair or replacement free of charge.
Damages due to accident, misuse, tampering or lack of prescribed
maintenance are not covered.
If service is required, contact the dealer from whom you purchased
the instrument. If under warranty, report the model number, date of
purchase, serial number and the nature of the failure. If the repair is
not covered by the warranty, you will be notified of the charges
incurred. If the instrument is to be returned to Hanna Instruments,
first obtain a Returned Goods Authorization Number from the
Customer Service department and then send it with shipment costs
prepaid. When shipping any instrument, make sure it is properly
packaged for complete protection.

Dear Customer,
Thank you for choosing a Hanna product. This manual will
provide you with the necessary information for the correct
operation of the meter. Please read it carefully before using the
meter. If you need additional technical information, do not
hesitate to e-mail us at tech@hannainst.com.

PRELIMINARY EXAMINATION

Remove the instrument from the packing material and examine
it carefully to make sure that no damage has occurred during
shipment. If there is any damage, notify your Dealer.
The meter is supplied complete with:
• HI 76302W 4-ring conductivity probe
• HI 3316D resistivity probe
• HI 70030 calibration solution sachet
• 9 V battery (not rechargeable)
• calibration screwdriver and instructions.
Note: Conserve all packing material until the instrument has
been observed to function correctly. Any defective item
must be returned in its original packing.

GENERAL DESCRIPTION

HI 87314 is a combination portable meter that can read conductivity
in 4 different ranges, and resistivity.
For conductivity measurements, the calibration is a simple 1 point
procedure through a trimmer located in the battery compartment, and
the supplied probe does not require recalibration when switching from
one range to another. The 4-stainless-steel-ring probe has a built-in
temperature sensor that automatically compensates for temperature
changes, and the temperature coefficient can be adjusted from 0 to
2.5% through a knob on the front panel.
For resistivity measurements, the meter is factory calibrated and, if
necessary, calibration can be adjusted by acting on the proper trimmer
located in the battery compartment. The HI 3316D resistivity probe is
easy to clean and requires little maintenance. It also features a built-in
temperature sensor to automatically compensate for temperature
variations, with an user-selectable (from 2 to 7%) coefficient.
Both probes use the same DIN plug on the top of the instrument, and
the meter automatically recognizes which probe is connected.
Hanna Instruments reserves the right to modify the design,
construction and appearance of its products without advance notice.
