Humidity Calibration
Graftel ISO/IEC 17025:2017-Accredited Humidity Calibration Services
For over 30 years, Graftel’s experience in the design, fabrication, application and calibration of humidity instrumentation. This has made us a humidity calibration resource for many industries.
We have the capability to calibrate all types and sizes of humidity instrumentation. Our chambers can control and measure humidity, pressure and temperature simultaneously.
Calibrations may be performed using air, nitrogen, helium, or custom non-explosive/nontoxic gases.
Our two-temperature two-pressure generator allows for extreme accuracy RH down to -80°C.
All humidity calibrations are traceable to the National Institute of Standards and Technology. (NIST) and are ISO/IEC 17025:2017 accredited.
Graftel maintains two NIST-traceable primary humidity calibration systems. Each is built around a single pressure two temperature generator. These two systems cover overlapping ranges so that they may be checked against each other. In addition, each system contains a working secondary standard. For more information as to our systems, please read below.
