DE-OX check test rebreather oxygen sensors under pressure


DE-OX® CHECK is the most up-to-date Check black smalldigital measurement instrument for checking partial pressure, milli Volt errors and response time of any oxygen sensor under pressure.

DE-OX® CHECK is a fully digital analyser that measures the output of up to three oxygen sensors simultaneously in an aluminium 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 pressurised up to 10 bar using air, oxygen or any known mixed gas from 0 to 100% oxygen. The pressure inside the test Check black small2chamber 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 (on request).
