Cleanrooms rely on precisely controlled pressure differentials to maintain air quality, prevent contamination and satisfy strict regulatory requirements. Positive pressure environments, common in pharmaceutical manufacturing, semiconductor fabrication and medical device production, use a pressure cascade to keep particulates and microorganisms out.
Negative pressure environments, such as containment suites and biosafety labs, use the same principle in reverse, ensuring hazardous materials cannot escape. In both cases, even a small deviation from the specified differential can compromise product integrity, patient safety or regulatory compliance.
Furness Controls designs and manufactures precision differential pressure instruments suited to the demands of cleanroom monitoring. Our instruments offer the high accuracy, long-term stability and low drift essential in environments where continuous, reliable measurement is crucial for quality management systems.
Standards and Accreditation
Our instruments and calibration services are designed to support the quality and compliance requirements of cleanrooms.
Furness Controls holds UKAS accreditation and operates in accordance with ISO/IEC 17025:2017 across our calibration laboratories in the UK, France, Germany, and the US. All calibrations are fully traceable to national standards.
Our instruments are suitable for use in programmes requiring compliance with:
