Thermo-Paramagnetic Sensor Thermo-Paramagnetic Oxygen Sensor
Oxygen is a paramagnetic gas, which means that it is attracted by a magnetic field. This magnetic susceptibility is much greater than that of most other gas molecules and therefore this physical property is ideal for the determination of the level of oxygen in a wide range of background gases.
Chilled Mirror Cooled Mirror
Michell’s Cooled Mirror Dewpointmeters are precision instruments for critical measurement and control applications. The fundamental nature of this method means that Cooled 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 optical principle utilised by Michell’s Condumax hydrocarbon dew-point analyzer is radically different from that of any other Cooled mirror instrument. Sensitivity of the order of 1ppm (molar) of condensate enables the analyzer to detect the almost...
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...
Michell Zirconium Oxide Oxygen Sensor Zirconium Oxide Oxygen Sensor
The zirconium oxide sensor utilized in our XZR-500 and XZR-400 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...
Quartz Crystal Microbalance The Quartz Crystal Microbalance (QCM)
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 vapour. Bulk adsorption of water vapour onto the coated crystal causes an increase in effective mass, which reduces the resonant frequency of the crystal...
