From The Kahn Companies

Moisture measurement continues to present designers of instrumentation with interesting challenges. For many years the moisture measurement industry has concerned itself principally with humidity ranges of -75?C dew point and upwards - in other words, moisture levels of greater than 1ppm. The sub-ppm range was seen as extremely specialized, requiring complex and expensive analytical tools.
