The most comprehensive temperature, humidity and dew-point calibration offering on the market today.
Read more...Michell Instruments and Rotronic, market leaders in the field of humidity and trace moisture measurements, offer a full range of temperature and humidity calibration equipment and systems.
These include transportable humidity generators for simple verification of relative humidity and temperature probes, pressure swing dryers and low dew-point generators for calibrating trace moisture sensors and instruments. As well as building custom-designed humidity and dew-point calibration systems, we also provide ISO/IEC 17025 accredited relative humidity and temperature calibrations in six locations around the world.
Our chilled mirror reference hygrometers provide fundamental, low-drift measurements of dew point. Use in combination with the Rotronic or Michell humidity generators for calibrations traceable to NPL and NIST national standards.
For cost-effective humidity calibrations on-site, these stable and reliable humidity generators can be used in combination with a chilled mirror reference for full traceability. Fully automatic, computer-controlled humidity calibration systems provide humidity generation, a climatic chamber and chilled mirror reference for professional calibrations.
Complete dew-point calibration package with optional compressor, dryer, dew-point generator, reference instrument and optional manifold. Capable of providing trace moisture calibrations down to -100 °C dew point
We have humidity, temperature and dew point calibration facilities located all over the world. Six locations are accredited by the relevant national accreditation agencies. Find out more about our ISO/IEC 17025 calibration facilities.
Expressed as a percentage, relative humidity is the ratio of the water vapor pressure to the saturation vapor pressure of the gas.
In simple terms relative humidity is the ratio of how much water vapor there is in the air compared to how much there could be before condensation occurs.
Calibration systems typically include humidity generators, chilled mirror reference hygrometers, and optional compressors or dryers for low dew-point calibrations.
The test chambers are designed to fit most probes and transmitters and there is the option for customizable probe sleeves.
Yes, all our calibration chambers have the option to program calibration cycles.
Both the HygroGen2 and HygroCal100 Advanced come with a relative humidity probe which doubles as a control element and a reference.
Ideally the reference should be more accurate than the instruments under test, this is where our chilled mirrors come in. All our calibration chambers can be used with a chilled mirror reference.Yes, our HG2-S calibration chamber is very often used for on-site humidity and temperature calibrations.
Process Sensing Technologies (PST) offers ISO/IEC 17025 accredited calibration services at several locations.
Dew point is the temperature to which you need to cool a gas for condensation to occur.
There is an option for customisable fittings, for large volume calibrations, the transmitter manifolds can be designed specifically for your connection type.
Ideally your dew point transmitters should be calibrated against a chilled mirror which has its own calibration traceable to national standards.
The DCS systems come with a chilled mirror reference as standard.Contact our experienced engineers to discuss your application needs.
