The role of humidity calibrations that are accurate, reproducible, and documentable is becoming more and more important. The humidity calibrator HUMOR 20 developed by E E is the ideal reference instrument for these requirements and is traceable to international standards. The HUMOR 20 can be used in the humidity range of 10-95% RH both for monitoring cylindrical sensors and also for monitoring instruments with cubic dimensions.
Based on its operating principle, the HUMOR 20 can be used under typical conditions in a laboratory climate. For operation HUMOR 20 requires only distilled water, filtered oil-free air with a pressure of 10 bar and a power supply between 90-230V AC.
The operation of the HUMOR 20 is based on a fundamental two-pressure process and thus is similar to instruments used in national bureaus for standards.
A range of complete, integrated calibration systems providing traceable calibration of humidity sensors in your own laboratory .
Calibration integrity in the field of humidity has never been more important than today. Product quality, process effectiveness, system maintenance and even human safety are all dependent on the knowledge that humidity is measured correctly - whether you are using low cost relative humidity probes to monitor manufacturing or storage facilities, or providing a high level trace moisture calibration service to a nationally accredited level. Our history of traceability goes back to 1982 when our systems were first compared with the NIST standard in Washington USA, and to 1986 when we became the first laboratory to be granted accreditation by the National Physical Laboratory, London under the United Kingdom Accreditation Service (UKAS). European traceability is achieved through EAL.
