Apera Instruments LabSen 213 Routine 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.
