Psychrometric calculator for HVAC engineers, designers, technicians, commissioning agents, and maintenance personnel. SI and IP units are supported.

- 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
-Humidity Ratio
-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.

Whats new

    Fixed display to be compatible with more devices.

Sketchy 2 property rule 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.

Love this app Everyone that is a painter need this app

Chris Bennett

Was a good app 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.

You gotta exit the app b4 u change refrigerants, got no probs here, good to go

David Wicker

Will not work on galaxy S4 Can not read display on S4

Karim Chamaa

Great Great app , it saves a lot of time. But can you include a drawing on the psychometric chart?

Tron Anon

As I expected 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.

It works well. It's easy to use. Android 4.1.2

Love it. 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.

Not able to read data on Galaxy S4 This app worked great on my last phone but not on my Galaxy S4

A Google User

Works like a charm! Simple, easy and gives all of the info expected w/o having to plot on a psych chart

Anthony Poukish

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.

It seems to work fine and the price is right! Thanks developer!


ok thank you. it's great simple app.

Pedro Hernandez

Does not work with not 3


Very nice app Real easy to use I only need to enter dry bulb and RH , calculated the rest for me, time saver

Gamiochipe Alberto

No bueno Not worth the space in my galaxy

Alex Hegarty-Coia

Great but.... This app is great but I want to see an ability to save your altitude.

A Google User

AIR LITE Thanks this works very well

Connor Barbour

Works perfectly All I can say is I'm so happy I don't need to use the chart any more. Great app.

A Google User

Good stuff 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.

A Google User

Works great Love this app. Would be nice to have some defaults or presets like altitude or gr/lbs dlm

A Google User

Great Just needs to be able to lock values.

A Google User

Thanks I take that back thanks! Didn't realize I didn't clear it out

kurt podschlne

Was a great app After last update rating went from 5 to a 1. Cannot use on note 3. Text blocks are all crammed together.

A Google User

Perfect As an industrial painter I have to take environmental readings all day, this is perfect, thank you

A Google User

Almost perfect Would be nice to use grains as a 2nd value with Db

A Google User

A Google User

Great Great and very handy. Saves a lot of time.

5 stars on my old phone, unusable in my galaxy s4.

sergey lapshin

Ser A little bit complicated and interface to be improve.

Sathya Nandan

Good one Simple and best

Rob Michael

Galaxy S4 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.

Agus Setyanto

Best of the best Best of the best

Nice little tool Handy for checking my work in my building science class. Numbers are a little off but only by a couple hundreds which is negligible in any real situation.

Rudyard Baker

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

Jagmohan Trehan

It is handy and very useful in troubĺe shooting.

David Faunce

Incomplete. 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.
