Apera Instruments LabSen842 User Manual

LabSen electrochemical sensors are premium pH electrode with manufacturing technology and key
components imported from Switzerland. LabSen842 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.

2.1 Connect electrode to S7-BNC cable, and then connect BNC 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,
