[Pressure] Request Recommendation for a Dial Manometer

[Samwrites]

I have a Resmed 10 Airsense and want to check it's reported pressure. I would appreciate a recommendation for a dial manometer and where I can buy one.

Thanks.

You would need a very sensitive one. It is easier to use a transparent plastic tube, make a U shape, and inject some water in it so you have two water meniscus in the U. At zero pressure, they are on the same level. You can read the pressure directly in water cm when connected to the CPAP.

Not a dial manometer, but a digital that I bought from Amazon and works well for checking CPAP pressure. I did have to fabricate an adapter to use the manometer fitting to the CPAP hose.

Thanks for the suggestions. I appreciate both of them.

Fill a tall flower vase or the like (taller in centimeters than your pressure in centimeters) with water and set it in a sink, shower basin, bathtub, or someplace like that where overflow won't make a mess. Disconnect your mask and with the machine running insert the mask end of the hose into the water. It will make bubbles, find the depth (in centimeters) that just makes the bubbles stop. That depth is the pressure in centimeters.

For example, if your pressure is 12 cm H2O, then a depth of 12 cm will be just enough to make the bubbles stop. Any depth less than 12 cm and there will be bubbles, any depth greater than 12 cm and there will be no bubbles.
