Air Lite Psychrometric Calcs
Inputs:
- Altitude
- Dry Bulb Temperature
And either:-Wet Bulb Temperature-Relative Humidity
- Dew Point Temperature
To Calculate:-Wet Bulb Temperature-Relative Humidity-Dew Point Temperature-Atmospheric Pressure-Barometric Pressure-Enthalpy-Humidity Ratio-Density-Specific Volume-Vapor Pressure
Calculations are made using The American Society of Heating Refrigeration and Air Conditioning Engineers (ASHRAE) Fundamentals 2009 ideal gas equations.
You must hit the clear button in between calculations. If more than three properties are filled in the application will default to using wet bulb as the humidity input.

Very good We have good experience Our work to easy with this app
Was great, now routinely crashes on my Note 9
I bought the Pro version long time ago, you remove it from me
Easy to use
You don't always need dry-bulb to solve. On a psychometric chart you can determine all properties from RH and Enthalpy or Wet-bulb and Humidity Ratio, over 20 different combinations most of which do not include dry-bulb.
The 2 property rule does not work for all properties. I tried dry bulb and humidity ratio...error. Dry bulb and enthalpy...error. Doing a quick calc for economizer, is best not attempted with this app.
I'm seeing a lot of comments of not working properly with Galaxy S4 but working just fine on mine. Settings? Not sure. It's a handy app though.
Unused it every day in a painter so need to know conditions I love thos app
Mode of data input is not useful for mechanical engineering analysis.
Simple app, with great features. I wish if it had better GUI
It is handy and very useful in troubĺe shooting.
Everyone that is a painter need this app
Simple and best
This app don't allows calculation of dry bulb above 60 degrees also it don't to plug in two information without the use of dry bulb information. This app need more working on
Best of the best
This was a good app. but it will not work on my Galaxy S4. The interface is all messed up ,the layout is shrunken the ad is in the way and you can't remove it. You can't see what your inputting or try to calculate. Tried to uninstall and reinstall it and still same thing. Guys get up with the times with the new O.S on android. Worked great on my old o.s.
Very nice, simple. Would be nice if when you hit enter in the dry bulb spot it would move to wet bulb, then hit enter & it calcs.
After last update rating went from 5 to a 1. Cannot use on note 3. Text blocks are all crammed together.
Real easy to use I only need to enter dry bulb and RH , calculated the rest for me, time saver
Love this app. Would be nice to have some defaults or presets like altitude or gr/lbs dlm
Just started learning psychrometrics in school and this app comes in very handy. Half the students in class have it. Definitely going to be using this in the field.
I just wanted something that I could plug in the numbers and have it calculate with out needing any data connection. There's a little bit more that i have no use for but it's not limited to just your temperatures and RH.
I downloaded this app with high hopes, but unfortunately it does not display properly with a HTC one. I could not see the text in the fields and was forced to copy-paste to see the one output I needed, humidity ratio. Also looking for an app where atmospheric pressure is an input rather than an output. Will raise rating if display problem is addressed.
All I can say is I'm so happy I don't need to use the chart any more. Great app.
Works like a charm! Simple, easy and gives all of the info expected w/o having to plot on a psych chart
I take that back thanks! Didn't realize I didn't clear it out
You gotta exit the app b4 u change refrigerants, got no probs here, good to go
As an industrial painter I have to take environmental readings all day, this is perfect, thank you
Not perfect. After putting values result is not perfect specially I followed mixing ratio.
