The HI60501 / HI60503 (PVC/PVDF submersible holders) together with HI60501‑2 or HI60503‑2 (PVC/PVDF
protective end caps), and HI605011 (mounting flange) provide a sturdy housing that prevents the probe from
being damaged. For high‑temperature/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 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 electrode holder (5).
