Dear Customer,
Thank you for choosing a Hanna product. This manual will

provide you with the necessary information for the correct

operation 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 tech@hannainst.com.
These instruments are in compliance with the directives

EN 50081-1 and EN 50082-1.

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:

• HI 7631/2 EC/TDS probe (HI 983304), HI 7632/2

EC/TDS probe (HI 983307, HI 983308), HI 7634/2

EC/TDS probe (HI 983303, HI 983306, HI 983309);

• Calibration screwdriver;

• 12 VDC power adapter.
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.
