DE-OX Check is a fully digital analyzer that measures the output of up to three oxygen sensors simultaneously in an aluminum pressure chamber. The sensor readings can be compared with the calculated value derived from the built-in digital pressure transducer and the test gas mix. The test cylinder containing the oxygen sensors can be pressurized up to 10 bar using air, oxygen or any known mixed gas from 0 to 100% oxygen. The pressure inside the test chamber can be finely adjusted for testing the sensors in any situation. The pressure chamber has an overpressure valve for safety.

DE-OX Check can be used by rebreather divers to check the error and linearity of their oxygen sensors. It can be connected to Personal Computers through serial port.
