This app calculates indoor humidity.Humidity is the amount of water vapor held in the air. (3)In that state, enter the indoor temp and tap the "ENTER" button. (1)First of all, calculate the dew point temperature from the outdoor temperature and the outdoor humidity using this app. With this function, for example, if you are calculating the outdoor dew point temperature from the outdoor temperature and outdoor humidity, and then the indoor humidity from the indoor temperature and the outdoor dew point temperature, then you can easily calculate the indoor humidity from the operations described below. The app has a function where if you press "TEMP." or "Wet Bulb" or "Dew Point" or "HUMID." or "HUM Ratio" or "Enthalpy" after performing a calculation, the value of the button you press will be retained and all other values will be erased. There is a way to alleviate the inconvenience caused by the large number of digits in this app. I’d suggest 3 significant figures or make it a user option. There are way too many digits in the output values. P.S : Thank you so much for you added one more star!
I'm sorry, I'm Japanese so I'm bad at English. This app calculates indoor RH% as you wish. All numerical values other than "Dew Point" are erased from the calculation result screen, and only the numerical value of "Dew Point" remains. (2)In that state, please tap the "Dew Point" button. (1)First of all, calculate the dew point temperature from the outside temp and the outside RH% using this app. The problem is solved if you operate the app in the way I will explain now. I sincerely apologize for the delay in my reply to you. At step 2 before entering the temp, press the dew point button first, then the dew point number will stay. Another minor thing is it displays too many digits. I have to memorize the dew point and re-enter it. But this calculator erases the dew point when I’m at step 2 entering the indoor temp. First calculate dew point of outside, then using same dew point and indoor temp, calculate indoor RH%. I need to calculate the RH% inside a house given the outside temp, outside RH%, and indoor temperature. We are not liable for any damage caused by the use of this application does not bear all of the responsibility. 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. If you enter an extreme value correct calculation result may not appear. Please input and use the temperature range(0 ℃ to 40 ℃ / 32☏ to 104☏ ) according to common sense as much as possible. ※ 2: Atmospheric pressure is fixed at the standard atmospheric pressure (1013.25hPa / 29.92inHg). ※ 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. The app can be used in Celsius temperature (℃) or Fahrenheit temperature (° F) and Click-Sound also can be of choice turned ON / OFF. If you enter an abnormal number (for example, high wet-bulb temperature than the dry-bulb temperature), makes us known in the error display. 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.
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).įor example, if you use this function, you can know specific-volume when you know dew point temperature and relative humidity. If you enter the any 2 of the items and tap “ENTER”, the app is automatically calculate other items. The app supports 6 items, "dry bulb temperature", "wet bulb temperature", "dew point temperature", "relative humidity", "humidity ratio" and "enthalpy".
If you use this app, you can very easily calculate humidity, dew point temperature, etc. # Psychrometric Charts means Humidity Charts. Very easy "Psychrometric Charts" calculator!. This is a HVCA tool already used in more than 20 countries worldwide! Very easy Humidity Charts calculator app!
