ResMed Autoset & humidifier
Is there anywhere that the percentage of humidity of the air for the temperature can be found?

For instance I have a climate line and the temp is set to 28 degrees c - what is the percentage humidity in the air?

Or is it just the temp of the air that is important?

There is no way to directly measure the RH.

I remember reading somewhere that you are getting around 80% RH at the various temps (depending on the RH/temp of the air going in).

IMO, turn the temp up until you feel like you are getting adequate humidification without the air feeling uncomfortable to you.

Both temperature and humidity are important in many applications. However, if all you know is the temperature you cannot find the humidity. You need additional information, such as the dew point, for example. The dew point is the temperature at which the relative humidity is 100% and you get rain out. If you knew both the temperature and the due point then you could, for example, use Diamaunt's chart to find the absolute humidity, which is the actual percentage of water in the air.

You can use an electronic sensor to measure RH. You can calibrate the sensor, if necessary, using a wet/dry bulb sling psychrometer.

There are other ways, too.
