Dear Customer,
Thank you for choosing a Hanna product. This manual will
provide you with the necessary information for correct opera-
tion 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 [email protected].
These instruments are in compliance with the
directives.
Remove the instrument from the packing material and
examine it carefully. If any damage has occurred during
shipment, immediately notify your Dealer or the nearest
Hanna Customer Service Center.
The meters are supplied with:
• Conductivity probe (fixed):
HI 7631/2 for HI 983304
HI 7632/2 for HI 983307 and HI 983308
HI 7634/2 for HI 983303 and HI 983306
• Calibration screwdriver
• 12 Vdc power adapter 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.
PRELIMINARY EXAMINATION
These instruments are specially designed to meet the needs
of simple continuous monitoring of conductivity or TDS.
The housing has been completely sealed against vapors and
humidity with IP54 rating.
You can simply hang the meter right above the sample to be
tested for continuous measurement.
All the meters come with a probe that compensates for the
temperature variation automatically. The probe is easy to
clean and requires little maintenance.
You can even select your own setpoint and be alerted of an
abnormal situation with a flashing LED alarm.
Measurements are highly accurate and the meters can be
calibrated at one point.
You no longer need to worry about battery changes either:
the unit runs without interruption on 12 VDC power supply.
