Precision measurements to ensure ultra-dry air in lithium battery manufacture

Ensuring ultra-dry conditions for lithium battery manufacture

Ultra-dry conditions are essential for any process involving lithium, which is explosively reactive with water. The quality of the batteries and the safety of the process depend on precise control of the micro-environment.

Drying the air is a significant expense which means precise measurements of moisture at the dryer outlets can lead to substantial savings in energy and a reduced likelihood of product loss due to damage.

The ability to cope with challenging conditions with high levels of contamination is a must for any instrument.

Precision measurements of dew point and trace impurities from a single supplier

Whether the process is contained in a glove box or a class 1000 (ISO 6) cleanroom, we offer a full suite of sensors and instruments as well as monitoring system for all parameters.

Our measurement capabilities include low dew points and trace moisture down to -120 °Cdp or 1 ppbV as well as trace oxygen and multiple trace impurities down to low parts per trillion.

Multiple trace impurities measurements are possible with a single analyzer system for maximum efficiency.

Benefit from a comprehensive offering for all crucial measurement parameters

Our dew-point transmitters, chilled mirror hygrometers and quartz crystal microbalance moisture analyzers offer precise, reliable trace moisture measurements, suited to different applications within the process. Our SIL-rated oxygen analyzers ensure process-safety.

Our trace impurities analyzers use highly sensitive plasma emission detectors to measure a wide range of impurities in the process, and, together with gas purifiers and stream selectors, provide complete assurance of inert gas purity.

The Rotronic Monitoring System (RMS) provides secure, cloud-based monitoring for all critical cleanroom parameters.
