Following the successful launch of its “PsycIt” Psychrometric iPhone app, Polygon, a global provider of property damage restoration, temporary humidity control and property performance services, has released a version for Blackberry users. ‘PsycIt’ delivers a valuable time-saving tool for site managers, quantity surveyors, architects and technicians by promptly and accurately calculating the amount of relative humidity on site, therefore quickly and precisely computing the time needed to efficiently dry the area.

“PsycIt” represents an interesting innovation in the assessment of psychometric calculations, including wet and dry bulb, vapor pressure, enthalpy, relative humidity, dew point and humidity ratio. Simple to use, it’s capable of calculating the most complex air-moisture combinations.  The most important benefit of this app is that it eliminates the need to use a cumbersome psychometric chart in the field.

“For the construction industry, delays in completing building projects lead to financial penalties, a loss of reputation and, ultimately, a loss of business in the long term. That’s why ‘PsycIt’ is an extremely valuable tool,” said Alex Kiffen, vice president of sales and marketing at Polygon.  “It quickly delivers a precise calculation of the climatic conditions so the user can be confident of the accuracy of the measurements and determine if they are keeping their building dry.”

Now available for both the iPhone and Blackberry, in Full or Lite versions, the app will be available for Android phones later this year. The Full version has the capability to calculate process loads as well as allowing mixing of multiple air streams. Both “PsycIt” apps enable easy input and output of ambient conditions, building dimensions, and promptly provide accurate readings in both imperial and metric.


Currently available in six languages, with more to be added soon, the Full version costs $7.99 and the Lite version is free to download on the Polygon website at
