Quartz Crystal Microbalance Quartz Crystal Microbalance
The Quartz Crystal Microbalance (QCM) technology for moisture measurement is based on monitoring the frequency modulation of a hygroscopic-coated quartz crystal with specific sensitivity to water vapor.
Chilled Mirror Chilled Mirror
Michell’s Chilled Mirror Dew Point Meters are precision instruments for critical measurement and control applications. The fundamental nature of this method means that Chilled Mirror instruments can be used as either extremely reliable and stable field instruments or as laboratory...
Impedance Impedance
Our Impedance hygrometers are rugged, low-cost, industrial measurement instruments for reliable moisture analysis from trace levels to ambient air conditions. They can be used in a wide range of gases, including hazardous area applications (flammable or explosive gases) and with many corrosive...
Calibration and Humidity Generation Calibration and Humidity Generation
Our humidity generators and calibration systems all use the same basic components and humidity generation principles. Clean oil-free compressed air or inert gas is fed into a pressure swing dryer, where virtually all the moisture from the gas is removed. The dryer uses high efficiency...
Hydrocarbon Dew Point Dark Spot Principle Hydrocarbon Dew Point Dark Spot Principle
The Dark Spot Principle The Dark Spot optical principle utilized by Michell’s Condumax hydrocarbon dew point analyzer is radically different from that of any other chilled mirror instrument. Sensitivity of the order of 1ppm (molar) of condensate enables the analyzer to detect the almost...
Capacitive Technology Capacitive Technology
Capacitive Technology Michell Instruments %RH sensors feature a capacitive thin-film polymer sensor. These sensors provide a high accuracy, excellent long-term stability and negligible hysterisis. They are insensitive to contamination by particulate matter are no...
Michell Zirconium Oxide Oxygen Sensor Michell Zirconium Oxide Oxygen Sensor
The zirconium oxide sensor utilized in our XZR500 and XZR400 ranges of Oxygen Analyzers is one of the most advanced sensors commercially available for measuring oxygen concentration. Unlike conventional zirconia sensors, which are often known as ‘air reference sensors’, the...
