Apera Instruments LabSen 803 User Manual

LabSen 803 Pure Water Combination pH Electrode
LabSen electrochemical sensors are premium pH electrode with manufacturing technology and key
components imported from Switzerland. LabSen 803 pH electrode is suitable for pure water
measurement, such as drinking water, distilled water etc.
This probe has following features:
 Impact-resist membrane (see the right picture), there is no
danger of electrode breakage during normal use.
 Movable sleeve, able to adjust infiltration rate of electrolyte.
 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,
which helps to improve the stability and service life of the
electrode.
 Fast heat conducting pH/Temp. combination structure (Swiss patented,
Nr.699927), increase sensing speed by 40%, refer to diagram-2.

2 How to Use the Movable Sleeve

As shown on the right picture, reference solution flows out of the small hole,
seeps through the tapered surface of movable sleeve. You may adjust the
degree of firmness when use, push up the movable sleeve to loose. If it is
too tight to push, please referring to the right picture: insert the probe into
the round tube (the accessory comes with the probe), and push down the
probe, then the movable sleeve will be loosen. Please pay attention to
remove the rubber plug when adjusting the movable sleeve, enables
reference solution flowing out of the small hole; then slowly rotate and
tighten the movable sleeve, so that there will be no air remain in the tapered
surface of movable sleeve, which can greatly influence the correct
measurement of the probe.

3 Usage and Maintenance

3.1 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.
