---- Very easy "Psychrometric Charts" calculator! ----
# Psychrometric Charts means Humidity Charts.
If you use this app, you can very easily calculate humidity, dew point temperature, etc.
The app supports 6 items, "dry bulb temperature", "wet bulb temperature", "dew point temperature", "relative humidity", "humidity ratio" and "enthalpy".
If you enter the any 2 of the items and tap “ENTER”, the app is automatically calculate other items.
You can refer to more items(plus 6 items) by use the app and sister app "HumidCalc" in combination(additional features since version 1.0.7).
For example, if you use this function, you can know specific-volume when you know dew point temperature and relative humidity.
Input range is the temperature is -273.15 ℃ to 99.97 ℃ (-459.67 ° F to 211.95 ° F), the humidity ratio is 0 kg/kg to 1 kg/kg (0 lb/lb to 1lb/lb) and the relative humidity is 0 %RH to100 %RH.
If you enter an abnormal number (for example, high wet-bulb temperature than the dry-bulb temperature), makes us known in the error display.
The app can be used in Celsius temperature (℃) or Fahrenheit temperature (° F) and Click-Sound also can be of choice turned ON / OFF.
※ 1: If you are using a 3.5 inches device, and if you want to change the setting of temperature unit or click sound, yu can change by the iOS device's Settings app.
※ 2: Atmospheric pressure is fixed at the standard atmospheric pressure (1013.25hPa / 29.92inHg).
- Disclaimer 1.
Please input and use the temperature range(0 ℃ to 40 ℃ / 32°F to 104°F ) according to common sense as much as possible. If you enter an extreme value correct calculation result may not appear.
- Disclaimer 2.
We are making as much as possible precise calculation result is output, but there are cases where errors due to technical problems, such as floating point results.
- Disclaimer 3.
We are not liable for any damage caused by the use of this application does not bear all of the responsibility.
Sorry for the very late reply.
Thank you for your high evaluation!
The "Calculator of Air" implements a memory function, and by utilizing this function, you can use this application even more conveniently.
As an example, we will explain how to calculate the relative humidity when outdoor air is taken into a room and then heated.
＊When humidification is not performed.
1: Enter the temperature and humidity of the outside air into the "Calculator of Air".
2: Press the "Dew Point" button.
3: Next, press the "TEMP." button and after entering the indoor temperature, press "ENTER".
With this simple operation, you can calculate the indoor humidity.
If you have a chance, please try it.
