These dissolved oxygen screwcap membranes are designed especially for Hanna's portable polarographic dissolved oxygen probes. The caps are constructed of durable ABS plastic with polytetrafluoroethylene (PTFE) oxygen permeable membranes. The membranes separate the cathode and anode of the probe from the water being tested. Oxygen diffuses across the membrane and interacts with the polarographic system to produce a current proportional to oxygen concentration. Each cap can easily be filled with HI7041 electrolyte solution and screwed on to the probe.
