Description

Five replacement membranes for Dissolved Oxygen probes.

When the PTFE membrane of the protective cap wears, it is always good to have a back-up.


The Hanna Instruments-76407A/P contains five replacement membranes.


The Hanna Instruments-76407A/P are spare dissolved oxygen screwcap membranes designed especially for Hanna’s portable polarographic dissolved oxygen probes. The caps are made from durable ABS plastic with polytetrafluoroethylene (PTFE) oxygen permeable membranes. Each cap is easily filled with electrolyte and installed on the probe.



  • Screw Cap Design

  • PTFE Membranes

  • Easily Fillable


The membranes separate the probe’s cathode and anode from the water being measured. Oxygen diffuses across the membrane and interacts with the polarographic system to produce a current proportional to oxygen concentration. Each cap is easily filled with Hanna Instruments-7041 electrolyte and screwed onto the probe.
