A point on the psychrometric chart can show 7 properties of air. If two properties are known then 5 other properties can be calculated. Air treatment will change the properties of air conditions. Changes in air condition can be determined by measuring each air properties and plotted on a psychrometric chart. One of the uses of psychrometric analysis is to determine the amount of cooling capacity used in air conditioning systems. To show the condition of the air at any time needed a system that is integrated between the data acquisition device and data display. This research designs and develops applications that are ready to display data and psychrometric charts that can later be integrated with hardware equipped with sensors through an interface. Psychrometric applications are designed using the JavaScript programming language, so they can be opened using any web browser. Psychrometric charts are drawn using iteration calculation methods. Based on the results of data analysis, the difference in value between the results of manual calculations and applications is as follows: wet-bulb temperature (Twb) is 0.27%, Moisture Content (ω) is 0.77%, specific enthalpy (h) is 0.52 %, Specific Volume (v) is 0.28%, Dew-Point Temperature (Tdp) is 0.92%.
