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:
• HI 1618D
amplified pH electrode with built-in temperature
sensor, plastic body and DIN connector
•
pH 4.01 & pH 7.01 buffer solution (20 mL sachet each)
• Electrode cleaning solution
•
Batteries (4 x 1.5V AA alkaline) and 12 Vdc adapter
•
Instruction manual and rugged carrying case.
Note:
Save all packing material until you are sure that the
instrument functions correctly. All defective items must be
returned in their original packaging together with the sup-
plied accessories.
HI 98140
and
HI 98150
are two of the most innovative portable pH
meters ever offered.
These instruments feature IP 67 waterproof protection, GLP (Good
Laboratory Practice) capabilities and use the
HANNA instruments
®
’
intelligent electrodes.
These pH electrodes incorporate a chip which memorizes the calibra-
tion data performed with a specific instrument. When the “intelligent”
electrode is attached to the meter again, it is automatically recog-
nized. This technology allows the operator to optimize time and
efficiency with unsurpassed safety. It avoids erroneous measurements
taken in the event the pH electrode is substituted after calibration.
This series of electrodes also incorporates a temperature sensor, elimi-
nating the need for an additional temperature probe.
HI 98140
and
HI 98150
feature all the most advanced features of
laboratory pH meters. Moreover they are provided with a dual level
LCD which facilitates operation in dimly lit locations.
By pressing a button, these meters can store up to 500 measure-
ments complete with date and hour. Stored data can be displayed
later or downloaded to a computer through an RS232 serial port and
the
HI 92000
Windows
®
compatibile software.
