Vaisala Corporation PRESS RELEASE
August 28, 2013
In 1973, Vaisala introduced HUMICAP®, the world's first thin-film capacitive
humidity sensor. Since then, Vaisala has become the market leader in relative
humidity measurements, and thin-film capacitive humidity sensors have developed
from one company's innovation into a global industry standard. Constantly under
further research & development, the Vaisala HUMICAP sensor is still the most
accurate and reliable humidity sensor on the market.
As the world's first thin-film capacitive humidity sensor, the HUMICAP was a
radical innovation that completely changed the way humidity is measured. Until
then, reliable humidity measurement was an unresolved challenge and hair
hygrometers were commonly used. The new ground-breaking technology had no moving
parts, and it was amazingly small due to the advanced use of thin-film
The innovation was originally designed for a
new radiosonde; however the
greatest interest for this revolutionary new sensor came from various industrial
customers. In fact, it marked the beginning of Vaisala's industrial business.
Continuous innovation of the sensor has developed INTERCAP, an interchangeable
humidity sensor, as well as HUMICAP variants which measure moisture in oil. The
fourth generation humidity sensor with improved stability and chemical tolerance
was introduced in 2006. The sensor is manufactured in-house from start to finish
in state-of-the-art cleanroom facilities at Vaisala.
Today, products based on Vaisala HUMICAP technology range from radiosondes to
hand-held meters to industrial transmitters. The sensor covers applications from
HVAC to the most demanding industrial and environmental applications, both
indoors and out. The sensor continues to offer superior performance in the most
demanding environments. As the HUMICAP celebrates 40 years, it also celebrates
its first year onboard NASA's Mars Rover Curiosity.
