are guaranteed for two years
against
defects in workmanship and materials when used for their intended purpose and
maintained according to instructions. Electrodes and probes are guaranteed for
six months. This warranty is limited to repair or replacement free of charge.
Damage due to accidents, misuse, tampering or lack of prescribed maintenance

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 Instru-
ments, first obtain a Returned Goods Authorization number from the Technical
Service department and then send it with shipping costs prepaid. When shipping
any instrument, make sure it is properly packed for complete protection.
The Hanna
pH 210
,
pH 211, pH 212
and
pH 213
are microprocessor-
based pH and Temperature bench meters.
pH 211
and
pH 213
can also measure ion concentration (ISE) and
Oxidation Reduction Potential (ORP) in the mV range.
pH measurements are compensated for temperature effect manually or
automatically with the
HI 7669/2W
temperature probe.
The instrument is equipped with a large easy-to-read LCD which shows
the pH (or mV) and temperature simultaneously, together with graphic
symbols.
The calibration process is guided step by step through clear indications on
the LCD. A stability indicator makes the calibration procedure error-free.
Through the RS232 serial port data can be transferred to a PC
(
pH 212
and
pH 213
only).
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 or the nearest Hanna
Customer Service Center.
