The DTS complements the MicroView ATEX Portable Hygrometer to enable sampling of various hazardous gases such as LNG. The hygrometer is maintained in its optimum position before and between sample measurements and the speed of response is optimised by keeping the sensor dry. The use of the DTS with the MicroView ATEX Portable Hygrometer creates a highly accurate and effective portable moisture analysis system.
One of the main ambitions of the food packaging industry is to extend the life of food products without reducing quality. One such method involves the sealing of foil wrapped foods using an inert gas which reduces bacterial activity and therefore ensures a longer shelf life. Most companies utilise nitrogen within this process but more specifically, nitrogen with an extremely low moisture content. With our experience and resources, we can work with the food packaging industry in the development of this low moisture nitrogen.
Sensitive equipment is often protected using a layer of gas as a way to buffer against shock and therefore be safeguard against damage. Unfortunately, blanketing gas can be affected if infected with water and this humidity can cause many different issues. The presence of water within the gas can cause corrosion, a reduction in sensitivity and changes in calibration. We can work closely with the manufacturers of instrument air and compressor systems to ensure that any water contamination is measured and recognised as soon as possible.
Products which utilise permeable membranes, for example bandages, must be put through stringent permeability testing prior to being sold. This testing allows manufacturers to gauge the overall quality of the product and therefore allows them to improve their design, if necessary. The overall testing process can be expedited when the moisture content is measured quickly and accurately. We can provide comprehensive and reliable moisture testing services which can be employed across a wide range of industries and sectors.
Another application which utilises blanketing gas is the refilling of oil filled transformers. The blanketing gas utilised within the vacuum evacuation and gas refill of oil filled transformers can be subject to water contamination. Any water content which finds its way into these gases can significantly affect the properties of the oil within the transformer. We can provide specialist moisture testing services which can help in reducing this type of contamination.
Calibration gases include gases which have been certified for resale. One of the requirements for certified gases is that all of the contaminants are measures and their concentrations stated. Water is one of the contaminants which needs to be measured. We can offer specialist moisture measuring services, for these and many other applications.
Another application which is relevant to our work involves the production of high density polyethylene. During production of polyethylene, moisture contamination within the ethylene feed gas can hinder the action of the catalyst and therefore slow down production. If you have any questions about our services within this area, please visit the website or you can contact us directly.
The manufacture of polymers requires feed stock and gases and it is these gases which can be affected by moisture contamination. To find out more, please visit the website or alternatively, you can contact our customer service team directly, by phone or email.
Large, stationary electricity generators are often kept cool using hydrogen. This is because of its high heat capacity and low viscosity. However, to maintain these properties, it must be kept dry. If contaminated with ambient moisture, hydrogen’s heat capacity will decrease and its viscosity will increase, compromising the safety and performance of the generator. Our hygrometers are used to monitor and control moisture content so that the hydrogen remains uncontaminated.

Virtually all engineering plastics used in the injection moulding process are able to absorb and hold moisture. This can have adverse effects on the quality of the finished product, both in terms of its strength (tensile and impact) and its appearance. The result is a reduced yield and an increase in the overall production cost. To ensure this does not happen, the plastic pellets used in the injection moulding process must be thoroughly dried, and the air that dries them must be completely free from moisture. MCM instruments are used throughout the plastics forming industries to control and monitor air humidity when drying pellets.
To ensure optimal performance of petrochemical reforming catalysts, it is important to maintain an optimal moisture/chloride ratio within the reforming reactor. If these are out of balance, the catalysts will suffer from high deactivation rates and decreased yields. The cost of an unbalanced moisture/chloride ratio can be very high in terms of yield losses, off-spec products, early catalyst replacement, processing problems and increased downtime. MCM provides highly accurate moisture monitoring and control instruments to ensure that this does not happen.
An Advanced Gas-Cooled Reactor (AGR) uses carbon dioxide gas to transfer heat from the nuclear fission core to the water boiler for steam generation. To avoid corrosion damage, moisture content needs to be continually monitored.
Our moisture meters are also used as boiler leak detectors or bulk moisture meters to ensure the safety and performance of boiler plant.

The presence of moisture in high-pressure natural gas supplied from production wells can have a number of adverse effects on infrastructure and gas quality. It can:
Moisture must therefore be measured at the point of extraction, at export stations, at gas storage locations and in the transmission grid.
Our moisture meters are used throughout the gas industry to maintain product quality and to preserve infrastructure. Find out more by visiting MCM online.
Having a reliable supply of breathing air is critical in many applications within the military, medical and fire fighting sectors. One of the things that can compromise the supply of air is the presence of excess moisture – this can lead to freezing in the pressure regulator and may cause ice to build up on the orifice, preventing air from reaching the user. This in turn can cause loss of life and equipment in submarines and aircraft. MCM instruments are used in many applications across various industries to control moisture levels and ensure a reliable supply of breathing air.
