Dew Point & Measurement
These products ensure peace of mind to thousands of customers around the world.
Trace moisture measurement is essential for ensuring quality, safety and efficiency in thousands of applications across a wide range of industries. Water vapour is a serious contaminant in many processes, having a detrimental effect on the quality and integrity of final products. Water dew point is a specific category of moisture measurement and is the most common parameter selected when condensation or ice formation is to be avoided.
Our wide range of instruments are designed by Michell Instruments and other PST brands for trace moisture and dew point measurement/analysis for several applications. Including applications for trace humidity range from medical breathing air and monitoring industrial dryers through to monitoring the dew point in natural gas to ensure it complies with international quality standards.
