oxygen sensor

Has anyone tried NRC D05R sensor for rebreather diving? I found their sensor is slightly cheaper than other Analytical Industrial and Vandagraph. I wonder if it has the same quality with them or not.

Hi all, I am trying to do a better job at monitoring my O2 sensors and have been measuring every time I calibrate both the ambient air reading and the pure oxygen reading at ambient pressure. I am then calculating the mV constant from both readings and checking the percent difference as a quick...

So basically I just wanted to share my experience and some graphs of my first O2 Sensor failure. I did a fresh water dive yesterday, water temp 4C, max depth 30m, dive time around 1h with no-deco, and when diving back to the entry at 10m of depth I had one of the three O2 sensors showed way...

Hello all, We've come across a few posts regarding Oxygen and CO sensors when testing Oxygen concentrations and the presence of CO, We'd like to help with any technical questions or support any members have. DD-Scientific

I wonder if it’s common practice to replace the O2 sensor cables/ harness when replacing the sensors every year. This is the JJ philosophy whose sensors already include the wiring. According to some the cables are prone to oxidation and hence may cause sensor failure even if the sensor itself is...

Please open and read @Bobby ’s article on oxygen sensors that is attached below. Once you have read it please answer the poll honestly. No one will know how you answered the poll. Several of us on here are attempting to determine the level of understanding that CCR divers have regarding oxygen...

Poseidon’s new state of the art oxygen solid state sensor is factory-calibrated and absolute, delivering unsurpassed operating life, shelf life and calibration stability. The sensor is similarly shaped to existing galvanic sensors for ease of replacement. For more information, go to...
