Dew Point Calculator

Before downloading, please check compatibility and operating environment specifications, as well as, other information such as applicable restrictions that may be included in "Read First".

Details The Dew Point Calculator generates dew-point temperature from the two channels of data which contain temperature and humidity data.
The resulting dew-point temperature data is added to a new channel of data.

Please make sure that three files exist in that folder.
Move the decompressed files to a desired folder to complete the installation.
To open, double click on the program itself, [DewPointCalculator.exe].
This application uses TRX files from our data loggers to automatically calculate dew-point temperature (the temperature at which moisture condenses on a surface).It is possible to open and view the generated dew point data in the Temp / Humidity Graph application and save the files in TRX format.
(This software uses the Sonntag equation to calculate dew point temperature)
  • We ask that customers using this software to be sure to make backup copies of the recorded data files (TRX format files) to be read by this application.
  • This application is being released as a Beta Version. Only use after agreeing to the statements written below under Disclaimers.

  1. Open a recorded data file with "Dew Point Calculator".

    Open the software by double clicking on the icon for the Dew Point Calculator.
    Click the [Generate Dew Point] Button and open the recorded data file you wish to use as a basis for the calculation.
    The recorded data must be of trx format and must include ONLY two channels: Temperature and Humidity.

    - To use this software with data from TR-73U or TR-74Ui loggers, go to the Temperature/Humidity Graph software wherein it is possible to erase the channels of data for recorded readings of data other than that of temperature and humidity and then save only those two channels of data as a TRX formatted data file.
    -To use this software with data from RTR-72 loggers, save the recorded data in TRX format.
  2. Generate Dew Point Data

    Select the method for creating the data file and click the [OK] Button to start the generating of the dew point data.
  3. Check the Generated Data

    Open the recorded data file in the Temperature / Humidity Graph to check and view the dew point data.
    The dew point data will appear in a newly created channel named [DPT].
    The newly generated dew point data can be used as other saved data; it can be viewed in a list form, printed out and/or output as text file (CSV format).
Ver. 1.00
  • Revised to make compatible with 64-bit Windows 7 (from December 1, 2010).
