2.6 Electrode Information

The Eutech EC 1720 conductivity meter is compatible with
2-cell and 4-cell conductivity electrodes with a DIN
connector. The Eutech EC 1720 conductivity meter can be
purchased in a meter only configuration (purchase
electrode separately) or kitted with a conductivity
electrode.
Refer to the electrode instructions for specific care and
maintenance procedures. The following are general
recommendations for electrode preparation.
Remove the packaging from the electrode and save
for storage.
Rinse the electrode using distilled water.
Connect the electrode to the meter.
The Eutech conductivity electrode included with the Eutech
EC 1720 conductivity meter kit has a nominal cell constant
of K = 1.0, built-in temperature sensor and 1 meter cable.
The ULTEM body housing has good chemical resistant
properties. The electrode design offers fast temperature
response and reduces air entrapment, ensuring accurate,
repeatable and stable readings.
The wetted materials of the electrode include:
• Polyetherimide (ULTEM) – protective guard
• Polybutylterphalate (Valox) – electrode housing
• Stainless Steel (SS 304) – two bands
The protective electrode guard can be removed
temporarily for cleaning; however, it must be re-attached
during measurement and calibration. Erroneous results will
occur while the electrode guard is removed.
Always immerse the electrode beyond upper steel band for
best results. Use the fill line on the outside of the electrode
guard for reference.
2.7 Meter Startup
Sequence
When the meter is powered on, it displays a set of startup
screens, starting with all segments lit screen, followed by
the meter info screen and then the meter self-test screen.
The meter info screen shows the meter model number and
current software revision.
After the meter info screen, the meter performs a series of
internal self-tests to verify that the meter is operating
correctly and then the self-test results are shown.
Finally, the meter proceeds to the main measure mode.
