Instruction Manual

HI 7635 - HI 7636

4-PIN IN-LINE

CONDUCTIVITY PROBES

Dear Customer,

Thank you for choosing a Hanna product.

This manual will provide you with the necessary information

for the correct use of the probe. Please read it carefully

before installing the probe.

If you need additional technical information, do not hesitate

to e-mail us at [email protected].

Hanna Instruments reserves the right to modify the design, construction and

appearance of its products without advance notice.

GENERAL DESCRIPTION

HI 7635 and HI 7636 are one-piece-molded conductivity

probes with pipe threads (1" NPT) at both ends.

This allows the probes to attach to an in-line system, and to

be used in conjunction with the HI 8936 conductivity

transmitters.

Measurements are highly accurate, and performed by using

a 4-ring potentiometric measuring method.

Probes require very little maintenance; the construction of

the housing is rugged, fiber-reinforced polypropylene.

HI 7635 also incorporates a built-in NTC sensor for tempera-

ture compensated conductivity measurements.

The max working pressure of these units is 5 bar (72.5 psi).

Do not use in systems where the temperature exceeds

80°C (176°F).

TYPICAL IN-LINE ASSEMBLY FOR HI 7635 (or HI 7636).

INSTALLATION

For the installation of the in-line conductivity probes, it is

necessary to use rubber seals between the probe and the

pipe or elbow joints. A pipe sealant is also recommended to

ensure a leak free joint. When screwing the joints, take care

not to overtighten as excessive pressures can cause the probe

damage.

The probes are supplied with a 4 m cable. The wires from

the cable must be connected to the HI 8936 process

Conductivity Transmitter as shown below. The connections

are color coded for an easy installation.

The probes can be compensated for normal contamination

by a process of re-calibration. However, it is recommended to

remove regularly the process conductivity probes from the

system for maintenance.

Deposits on the probe can be removed by immersing it in

0.1N Hydrochloric acid for about 30 minutes. Heavier

deposits may demand longer immersion time.

Clean the electrode thoroughly with water prior to the

reinstallation. On reinstalling, check the seals carefully to

ensure a leak connection.

Note: Always recalibrate the meter when attaching a new

probe.
