      Description

      The Model 420 is a membrane covered galvanic oxygen probe with built-in two-wire 4-20 mA transmitter. The probe is connected to a DC supply and draws a current of between 4 and 20 mA corresponding to the oxygen concentration.

      There are only two wires to connect, and there is no limit to cable length. The output signal is galvanically isolated from the built-in electronics and the process fluid. Interference between the Model 420 and other equipment can never occur!

        The OxyGuard Model 420 can therefore be connected directly to a wide range of equipment that can accept a 4-20 mA input, such as alarms, indicators, controllers, recorders, PLC’s, PC systems with A/D input etc.

        The Model 420 can also be used to measure gaseous oxygen concentration

      • Key Benefits
        Extremely High Stability -zero adjustment is never needed, calibration seldom
        No regular maintenance needs. The robust membrane is easily cleaned, but if damaged can be easily replaced
        Correct measurements with flow as low as 1cm/s
        Based on a chemical principle superior to that of traditional DO probes
        Galvanic type - True Zero
        Built0in temperature compensation
        No practical limit to cable length
        Wide range of armatures and fixtures - e.g. the AirAlam for worker safety in areas where fluctuating oxygen levels could occur in the air
