The oxygen probe body is made of PEI.
A temperature sensor provides temperature measurements of the sample.
Use the protective cap when the probe is not in use. To replace the membrane
or rell with electrolyte, proceed as follows:
Remove the protective shipping tube by gently twisting and
pulling it o the body of the probe (see g. 1).
Unscrew the membrane cap by turning it clockwise (see g. 2).
The new membrane cap supplied with the meter should be rinsed
with electrolyte solution. Rell with clean electrolyte solution.
Gently tap the sides of the membrane cap to ensure that no air
bubbles remain trapped. Do not tap the bottom directly with your
nger, as this will damage the membrane.
Make sure that the rubber O-ring sits properly inside the membrane
cap. With the sensor facing down, slowly screw the membrane cap
clockwise. Some electrolyte will overow.
