First of all, please be sure to click "* Caution: Check the handling instructions / link" to check the handling instructions.This software was created so that you can check the calculated value instead of reading the value of "dew point temperature" from the psychrometric chart.For the dew point temperature, calculate the "dew point temperature of clean water", "dew point temperature of supercooling", and "dew point temperature on ice".Enter the temperature and humidity and click the "Calculate" button.(Note: The calculation will take some time.)-The temperature input reference value is -10 ° C to + 50 ° C.You can also enter -40 ° C to -10 ° C and 50 ° C to 100 ° C, but use them as reference values.-The input standard value of humidity is 0% to 100%.Humidity of 100% or more is not in reality, but it is possible to input up to 300%, but it is numerical. Please use it as a reference value.-The standard value of atmospheric pressure is 1013.25hPa.You can change the numbers as needed.It is 1013.25hPa or less to 850.0hPa or more.If it exceeds each standard value, be careful when handling the numerical value.As a result of entering the numerical value, the following numerical values are displayed in addition to each dew point temperature."Absolute temperature (K) ℃" "Saturated water vapor pressure hPa" "Humidity% water vapor pressure hPa" "Humidity% water vapor pressure kPa" "Humidity% water vapor amount g / m3" "Humidity% absolute humidity kg / kg "Humidity% wet-bulb temperature ℃"The saturated water vapor pressure of water is calculated by the SONNTAG formula.Also, refer to JIS Z8806: 2001 "Humidity-Measurement method".There are various other formulas for calculating the saturated water vapor pressure, and there are some errors from the actual situation, so we do not guarantee all the values. In reality, there are various conditions, so please consider them when using.
