LabSen 213 Routine 3 in 1 pH Electrode
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 (Swisspatented, Nr.699927), increase sensing speed by 40%, refer to diagram-2. Diagram-1 Diagram-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. 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.
