The critical element in any measurement system is an accurate and reliable sensor. The OxyGuard Stationary Probe meets these criteria for the measurement of oxygen.

The Stationary's robust construction and simple design make maintenance and servicing easy. It uses a strong, easy-to-clean and easy-to-change membrane in a screw-on membrane cap. Regular servicing is not required. When necessary probe can be fully overhauled in five minutes.

The probe design uses a galvanic cell with built-in temperature compensation. It produces a millivolt output proportional to the oxygen present in the medium in which it is placed. The probe consists of two parts: an upper part housing the electronic circuitry, stainless steel calibration screw, cathode and anode; and a lower part comprising a screw on membrane cap with fitted membrane. The cap is filled with electrolyte and simply screwed onto the upper part.
