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. The probes are warranted for a period
of six months.
This warranty is limited to repair or replacement free of
charge. Damage due to accidents, 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 problem. 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 ship-
ment costs prepaid. When shipping any instrument, make
sure it is properly packaged for complete protection.
Dear Customer,
Thank you for choosing a Hanna Product.
Please read this instruction manual carefully be-
fore using the instrument.
If you need additional technical information, do not
hesitate to e-mail us at [email protected]
These instruments are in compliance with the
directives.
PRELIMINARY EXAMINATION
Remove the instrument from the packing material
and examine it carefully to make sure that no dam-
age has occurred during shipment. If noticeable
damage is evident, notify your dealer.
Each meter is supllied complete with HI 1288 probe,
batteries, rugged carrying case and instructions.
Note: Save all packing material until you are sure
that the instrument functions correctly. All
defective items must be returned in the origi-
nal packing together with the supplied ac-
cessories.
GENERAL DESCRIPTION
HI 991300 and HI 991301 have been designed to
offer you the combination of pH, electro-conductivity,
total dissolved solids and temperature measurements.
To increase precision, two models are available,
with different conductivity ranges, for applications from
purified to brackish waters.
All operations and settings, including calibration buff-
ers and temperature scale selections, are made
through only 2 buttons.
The housing is waterproof and rated for IP 67 con-
ditions.
The supplied multi-parameter probe, HI 1288, in-
cludes pH, EC/TDS and temperature in one conve-
nient, rugged handle. In addition, to ensure against
interference from transient electrical noise, a solid-
state amplifier is integrated into the probe.
Other user selectable features include different TDS
factors from 0.45 to 1.00, and a range of tempera-
ture coefficients (
β
) from 0.0 to 2.4% for greater
consistency and reproducibility.
