Replacement Procedure - Extech Instruments DO210 User Manual

Probe Head Replacement
The probe head (on the tip of the probe) holds a thin Teflon® membrane and an electrolyte
container. Calibration errors or reading errors could indicate loss of electrolyte or a
dirty/damaged membrane. The membrane is very delicate and can easily be damaged if it
comes in contact with solid objects. Replacement probe heads are available from an Extech
distributor.
Replacement procedure
1. Unscrew the probe head and empty the old electrolyte from the container.
2. Fill the new probe head/electrolyte container with electrolyte.
3. Screw the probe head onto the probe handle. Excess electrolyte may be forced out through
the threads. Wipe clean.
4. Lightly tap the probe to remove any air bubbles.
