Apera Instruments LabSen843 User Manual

LabSen electrochemical sensors are premium pH electrode with manufacturing technology
and key components imported from Switzerland. LabSen843 adopts special H glass
membrane, suitable for high temperature and strong base solution.
This probe has following features:
⚫ Impact-resist membrane (see the right picture)，there is no danger of
electrode breakage during normal use.
⚫ Tested in high temperature and strong base condition, the service life of
the probe is 5 times longer than normal electrodes (test condition: 60°C,
1M NaOH solution).
⚫ Blue gel inner solution, does not flow and will not cause bubble.
⚫ Silver ion trap reference prevents the contamination of the junction when
testing sample contains sulfides and proteins.
