Description

TQC Dew Point Calculator

TQC Dew Point calculator is a handy tool to determine dew point temperature based upon the measurements from sling psychrometer . The measurement unit is available in Celsius and also Fahrenheit converter.

The simple calculator for determining the dew point and relative humidity using the measurements, carried out with a Slinger psychrometer (measured in the wet / dry bulb principle) or an Electronic Temperature and also Relative Humidity meter.

Standard ISO 8502-4

Calculate the dew-point, which is a logarithmic function of the vapour pressure at the actual temperature. There are tables or charts from which the dew-point can be determined. Their parameters are air temperature and relative humidity at a given atmospheric pressure. Such as table is given in Annex A. Commercial dew-point calculators of sufficient accuracy may also be used.

NOTE     The figures are mean values for air temperatures from 0 °C to 35 °C. For a given air temperature, more accurate figures can be obtained from Annex A.

 TQC Dew Point Calculator DETERMINATION OF VALUES

  1. If a sling psychrometer, so called wet- dry bulb temperature is being
    • After that is determine the dew point by putting the dry bulb temperature (upper white scale 1) against the wet bulb temperature (upper black scale).
    • Read the dew point in the window 2 against the earlier determined wet bulb
  1. If an electronic Temperature and also Humidity meter is being used.
    • Next step is determine the dew point by putting the black arrow on the lower scale 4 (Relative Humidity % RH) against the measured RH value in the measured RH value in the windows.
    • Finally focus on the measured temperature at scale 3 and read the dew point on the lower black scale (Dew Point).

For Example:

Dry bulb temperature:

25°C

Wet bulb temperature:

19°C

Dew point:

16°C

Relative humidity:

58%
