Reliable measurements for moisture and water vapor

Why measure moisture?

As a contaminant, moisture can significantly affect product quality and process efficiency. It may reduce productivity, damage equipment, and cause unplanned downtime. The accurate measurement of H₂O levels in process gases depends on using the right sensing technology to suit each application. As the expert moisture analyzer manufacturer, Servomex offers a wide range of sensing technologies, powering industrial moisture analyzers in a variety of processes including semiconductor manufacturing, medical gases, and air separation units.

Our solutions

Servomex offers a range of sensing technologies for moisture analysis, ranging from ppm-level analysis to the lowest ultra-trace measurements available.

• Aluminum Oxide sensors work by measuring the capacitance between the aluminum core and a gold film deposited on the oxide layer. The capacitance varies according to the water vapor content in the pores of the oxide layer.
• Gas Filter Correlation sensing is an advanced Infrared-based measurement technology based on the unique light-absorbing properties of some gases. It performs effectively where extremely accurate, low-level measurements are needed, or where background gases may interfere with the measurement.
• Infrared sensing is a flexible measurement technology based on the unique light-absorbing properties of some gases, delivering a non-contact, real-time detection of the selected gas’s concentration in a mixture.
• TDLAS moisture sensing is a specially configured version of our Tunable Diode Laser sensor which is highly specific to moisture, and offers a fast, highly stable, continuous measurement.
