TABLE OF CONTENTS
The HI 9210N heavy-duty pH meter is designed to provide laboratory results
and accuracy under the harshest of industrial conditions.
The supplied HI 1217D rugged pH electrode, incorporates a temperature
sensor to provide both pH and temperature measurements with one probe.
The electrode signal is also preamplified and strengthened to give you
better protection against noise and electromagnetic interference, a common
phenomenon in industrial applications.
Calibration is manual to assure that the unit can be calibrated at any pH
buffer value. The trimmers for calibration are placed behind a protective
cover, that also keeps the meter watertight and prevents the calibration
from being tampered with.
A low voltage indicator appears on the screen to alert the user that there is only
a few hours of battery life left. Afterwards, the BEPS (Battery Error Prevention
System) will stop any false readings by shutting the meter off.
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
noticeable damage, notify your Dealer immediately.
The instrument is supplied complete with:
• HI 1217D pH electrode with built-in temperature sensor,
DIN connector and 1 m (3.3’) cable
• Batteries, 4 x 1.5V AA
• Instruction manual
Note: Save all packing materials until you are sure that the instrument is
functioning correctly. Any damaged or defective item must be
returned in its original packing materials together with the supplied
accessories.
