The HI60501/HI60503 (PVC/PVDF submersible holders) and HI605011 (mounting flange) provide a sturdy
housing that prevents the probe from being damaged. For high‑temperature or complex chemical processes it is
recommended the use of PVDF accessories.
To install the probe:
A. Unscrew the protective end cap (9).
The cap allows for quick and simple probe maintenance and replacement.
B. Slide out the electrode holder cap (3).
C. Screw the probe into the internally threaded protective cap (9), step I.
D. Screw the probe and protective cap subassembly onto the holder (5), step II.
E. Feed the probe cable through the holder (5) and out through the cap (3) and cable gland on top (2). The
cable is shielded inside the holder to prevent any damage to the insulation.
F. Tighten the cable gland (2), step III, and slide the cap (3) back onto the holder (5).
