Title: 02 sensors Post by: onwardsupwards on August 28, 2008, 09:38:44 PM Any one know if keeping 02 sensors in the fridge extends life?
Title: Re: 02 sensors Post by: JD on August 28, 2008, 10:11:09 PM No. The only way to keep the reaction from occuring is to keep them in an inert environment. If you put them in a sealed bag of argon or CO2 it will stop the reaction. The only problem with doing this is they need to be out in the air to start the reaction again for a few hours.
How long do you keep your sensors for? The deterioration is linear, so I change mine every 12 months in Bernald. For example, if a new sensor can read 2.0 ppO2, they slowly read less and less, so after 12 months the maximum it can read may be 1.7. It may take 2-3 years to get to a point of not being able to read 1.0 (ie, 100% O2 at1 ata), so after I am finished with them, they are still useable in a sensor. If you get the right connector for your analyser, I will give you a constant stream of them.

While keeping your O2 sensors in the fridge doesn't extend the sensor life, it is highly recommended for regulators and regulator O-rings. The cooler conditions reduces the thermal cycling, hence expansion/ contraction of the regulator bodies and damage to O-rings. Hence I recommend you keep all your regulators in the fridge.

You should always keep your drysuit in a cool environment with not a great deal of temperature fluctuation, so the fridge is a great spot.

I would think PH would have the best kept dive gear of us all. After all, he keeps his dive gear in his house... PERMANENTLY ! :) Title: Re: 02 sensors Post by: PMH on August 29, 2008, 02:30:24 PM RN, While keeping your O2 sensors in the fridge doesn't extend the sensor life, it is highly recommended for regulators and regulator O-rings.

IT dinner party at Ians...the foods off but hey you get to suck on a nice cold reg at the end of the night???
