The world's largest range of moisture and hydrocarbon dew point analyzers for the oil, natural gas, refining and power industries.

Our analyzers use one of four measurement techniques so you can be sure to always have the best technology to suit your application:

  • Tuned Diode Laser Absorption Spectroscopy (TDLAS) - The next generation TDLAS Analyzer for automatic online measurement of moisture in variable compositions of natural gas and biomethane. Michell TDLAS products employ the latest techniques in laser absorption spectroscopy and signal processing power to offer a robust high performance analyzer, designed specifically for the measurement of moisture in natural gas.
  • Ceramic Impedance Sensor - Michell's proprietory sensor for trace moisture in gases and moisture in liquids. A cost-efficient and reliable solution.
  • Dark SpotTM - A specially developed sensor based on the chilled mirror to measure hydrocarbon dew point in natural gas.
  • Quartz Crystal Micro Balance - highly accurate and fast measurements of trace moisture in gases.
Sampling Systems
Sampling systems are essential to ensure a representative sample for analysis. Our analyzer packages combine the latest Michell moisture sensing technologies with engineered sample-conditioning systems to create a reliable and easy to operate on-line instrument.

Standard sample packages are available for core applications such as glycol dehydration of natural gas; transmission quality of natural gas; and feed gases and liquids for catalytic reference processes. If your needs are not covered by our standard designs, our systems engineering department offer customised design and build services for analyzer packages.

The analyzers and sampling systems in the range are designed to meet world wide safety standards from ATEX, IECEx, FM, CCSAUS and GOST-Ex. .
