QMA601 The next generation Advanced Quartz Crystal Microbalance analyzer from Michell Instruments is designed to provide reliable, fast and accurate measurement of trace moisture content in a
wide variety of process applications where keeping moisture levels as low as possible is of critical importance.
Promet I.S. Promet I.S. Instrinsically Safe Process Moisture Analyzers measure high pressure, process gases and
vaporized liquids on natural gas platforms and terminals, petrochemical plants and industrial gas manufacturing facilities.
Up to four Promet I.S or Liqudew I.S analyzers may be combined via the Multi-Channel Control Unit.
Promet EExd A heavy-duty analyzer for moisture in natural gas,
the Promet EExd is housed in an flame-proof/explosion-proof enclosure, certified to ATEX, CCSAUS and GOST.
Designed for simple installation and integration into the plant, the Promet EExd is configurable for single or dual channel measurements of moisture.
Liquidew I.S. The Liquidew I.S. Instrinsically Safe Moisture in Liquids Analyzer, provides fast and reliable on-line
measurement of moisture content in liquids. A wide variety of non-polar liquids can be measured continuously,
on-line, including flammable liquids and petrochemicals.
Condumax II On-Line measures the hydrocarbon dew point of natural gas, a critical factor in ensuring the quality of the gas.
The analyzer includes optional water dew point measurement, to increase safety as well as avoid damage to pipelines and turbines.
