Environmental Chamber Humidity and Temperature Measurement

Test chambers are invaluable tools within industrial manufacturing that ensure the quality of products such as low-emission batteries for vehicles, switchgears, connectors, fiber optics, cell phones, pharmaceuticals and different types of electronics and cables. The chamber types vary from small, to walk-in, or even drive-in chambers. 

The climate within a chamber is something we can control, but that requires accurate measurement data. Although the measurement module is usually on the back wall of the chamber, it is integrated into the component board being one of the most important elements of the equipment as it defines the accuracy of the chamber and the reliability of the tests that have been done with it. A very common test of 85 % relative humidity in 85° C has been moving to more demanding conditions up to 95 % relative humidity and 95° C. This requires a measurement technology such as Vaisala HUMICAP® that not only tolerates these conditions but also measures reliably and accurately for years.
