Apera Instruments LabSen 213 Routine User manual

LabSen 213 Routine 3-in-1 pH Electrode
User Manual
LabSen electrochemical sensors are premium pH electrode with manufacturing technology and key
components imported from Switzerland. LabSen 213 routine 3-in-1 pH electrode is suitable for
routine lab use, integrates ATC probe, especially suitable for high-precision pH measurement of
scientific research and quality control.
This probe has following features:
Impact-resist membrane (see diagram-1), there is no danger of
electrode breakage during normal use.
Blue gel inner solution, does not flow and will not cause bubble.
Long life reference system, has better stability and service life.
Fast heat conducting pH/Temp.combination structure (Swiss
patented, Nr.699927), increase sensing speed by 40%, refer to
diagram-2.

2 Use and Maintenance
2.1 Connect BNC & RCA plug to the input on the pH meter.
2.2 When measuring, please unscrew the bottle cap, pull out the electrode and rinse it with
deionized water. After using, please put the electrode back into the bottle and screw tight the
cap.

Diagram-2
Before pulling out or putting back the
electrode, make sure to fully loosen the blue
cap on the storage sleeve so that the
electrode can move in and out smoothly.

2.3 Prior to measurement, remove the rubber plug to maintain pressure of the reference solution,
keep consistent flow rate of reference solution and stable potentials of junction.
2.4 After a period of usage, the reference solution will running low. Whenever the level falls to 1/2
height of the electrode, add 3M KCL solution to the refilling hole by using syringe or pipette.
2.5 The connector of the electrode should be kept clean and dry. If being contaminated, please
clean it with medical cotton and absolute alcohol and blow dry to prevent the short circuit of the
electrode and slow reaction of electrode.
2.6 The electrode measuring tip should be soaked in the soaking bottle containing certain amount
of storage solution to keep the membrane hydrated and junction unblocked. Clean the bottle
and replace the storage solution if the storage solution gets turbid and mildewed. The electrode
should never be sinked in pure water or buffer solution for long.
2.7 Please avoid measuring dehydrated medium like strong acid or alkaline solution, absolute ethyl
alcohol and concentrated sulfric acid. In case of measuring such solution, please try to reduce
the immersion time and clean it carefully after use.
2.8 After 1-year of use, we recommend replacing the electrode to ensure the best accuracy.
