Reliable and accurate measurements optimize efficiency for cleaner, cheaper and safer energy production

We Know Your Challenges

Ensuring that energy is produced cleanly, efficiently and safely is a key driver for all energy producers, whether this is in renewable energy or for coal-fired power stations. This industry is fast-evolving as new technologies together with legislation drive change and development. Energy producers require reliable measurements to monitor critical parameters at all stages of the energy production and supply.

Helping You is Our Business

Reliable measurements of moisture and other trace impurities help to protect equipment and reduce the costs of routine maintenance as well as helping to make energy production as efficient as possible. As well as reducing the monetary cost, we provide measurements that help to reduce the environmental costs of energy production. For example, by reducing harmful emissions and ensuring fuel is used as efficiently as possible.

What We Measure

We offer reliable and accurate measurements of the parameters required by power generation and maintenance companies:

•trace moisture
•relative humidity
•trace impurities in pure gases
•hydrogen purity
•trace oxygen
•hydrocarbon dew point
