InPro 4010 pH electrode
3. Check the membrane chamber of the electrode for
the presence of any air bubbles and remove same
by lightly swinging the sensor in a vertical plane.
4. Please refer to the instruction manual of the relative
housing in order to install the sensor.
5. Connect the sensor to the pH transmitter,
using a cable with VP (Vario Pin) connector.
Please refer to the wiring and terminal diagram
accompanying the cable.

Calibration and measurement

InPro 4010 sensors require 2-point calibration. The
sensor is then dipped in succession into two different
buffer s olutions with given pH reference values and the
transmitter calibrated to these buffer values. Please
refer to the i nstruction manual of the transmitter for
details.

Maintenance

The sensor with polymer electrolyte cannot be refilled.
The sensor must not be stored dry. In the event that
the sensor dries out, it is necessary to recondition
it before use by immersion in FRISCOLYT™ (Order
No. 51 340 053) for at least 24 hours. InPro 4010
sensors should be stored with fitted watering cap
containing FRISCOLYT. After each working cycle, the
sensor tip and the apertures (diaphragms) must be
thoroughly cleaned using deionized water.

Removal of dirt and residue

1. Sluggish response time. The glass membrane
can be reactivated using a HF solution (Order No.
51 319 053). Only that section of the sensor tip
below the two (diaphragms) apertures may be
immersed in the HF solution, and this during a
period of about 5 minutes. Immediately afterwards,
rinse the sensor thoroughly and immerse in
FRISCOLYT for at least 12 hours.
2. Insufficient sensitivity (slope). Check the
apertures for contamination and rinse with warm
water. Check the VP connector for traces of
moisture. If necessary, clean well using deionized
water or alcohol, and afterwards dry carefully.

Disposal

If no relative official regulations are in force, used or
defective InPro 4010 sensors and the packaging can
be d isposed of as ordinary household waste.
