We see from your search that you're looking for information on the term "Relative Humidity",
and we have a large number of manufacturers' news releases and technical articles here on Laboratorytalk which will be of interest.
Let me be your guide.
Start with
the news release Humidity sensor copes with chemical interference from
Vaisala, which we summarised at the time by saying "Humicap180R sensor has been tested in laboratory conditions and performs better in both laboratory high chemical concentration tests and in long-term field stability tests".
A few weeks before,
we featured the news release Creating the right environment in chambers from
Progen Scientific: "Available from Progen Scientific the SGC110, made by Weiss GallenKamp, is available in a variety of guises and offers a host of features and benefits".
In May 2007, we covered the news from ETL Group
concerning its Met3 and the Met3A
- take a look at High quality meteorological measurement systems
which says: "Integrated systems are housed in environmental enclosures for stand alone, indoor or outdoor mounting, installation hardware and software are included, with optional interface cabling".
Take a look also at the news release from Copley Scientific, Flow controller for dry powder inhaler testing,
as well as Gravimetric analyser handles moisture sorption from Meritics,
and Moisture measurement slide rule calculator is free from Michell Instruments.
