DULCOMETER

D1C Measured Variable pH and DULCOTEST

PHEP or

PHER Sensor for pH, Maintenance

Controller

The

DULCOMETER

controller type D1C for the measured variable pH is maintenance-free.

Sensor

IMPORTANT

• The sensor is to be regularly serviced to avoid any excess metering caused by a sensor

failure!

• Observe the valid national regulations for maintenance intervals!

• Do not touch the electrodes or bring into contact with greasy substances!

Maintenance interval

monthly

Maintenance

Work

The sensor should regularly (once a month) undergo a visual check and be cleaned if necessary.

If deposits on the glass electrode withstand cleaning with a soft, moistened cloth, the following

cleaning agents may be used.

Kind of deposit

Agent and duration of application

General deposits

Non-abrasive household cleaner

Scale or metal hydroxides

Diluted hydrochloric acid (approx. 0.1-3 %, 1-5 minutes)

Oil, grease

Solvents, like alcohol or acetone

Biofouling

Mixture of diluted hydrochloric acid and pepsin, several hours
Solvents (e.g. acetone) must not be used to clean electrodes as
they can demage the plastic stems.

It is essential that the sensor are rinsed thoroughly after having been cleaned.
