The HI 6054 is a rugged, fiber-reinforced polypropylene in-line electrode holder.
Simply install the holder in the line so that liquid will always be present inside the holder.

Once installed, the electrode will remain in contact with the fluid at all times, allowing the most accurate readings possible.

The HI 6054B and HI 6054T are designed specifically to work with HANNA electrodes with external thread of ¾" x 16 UNF and PG 13.5 respectively.
