PLACID Instruments manufactures precision measurement microphones, preamplifiers, and data acquisition systems from our facility in Utrecht, The Netherlands. Every instrument is designed to deliver measurement results that are traceable, defensible, and suitable for use in regulatory compliance, scientific research, and industrial quality programmes. We build to European standards and calibrate in an ISO/IEC 17025 accredited laboratory — so you can stand behind every number your system produces.
Our product range covers the complete acoustic and vibration measurement signal chain. From the microphone capsule through preamplifier signal conditioning to multi-channel data acquisition, each component is specified, matched, and calibrated to work together. Whether you are measuring environmental noise for a planning inquiry, characterising the NVH of an electric vehicle, or determining sound absorption coefficients of a new building material, PLACID systems give you the measurement uncertainty documentation that underpins a credible result.
ISO/IEC 17025 accredited calibration is not a marketing distinction — it is the documented evidence that your microphone's sensitivity has been measured by a laboratory whose competence has been independently assessed, using methods traceable through an unbroken chain to national measurement standards. When a noise measurement result is challenged in a planning appeal, a health and safety investigation, or a product certification audit, the calibration certificate is the first document reviewed. Factory QA/AC certificates confirm production quality checks. Accredited certificates confirm measurement uncertainty values that you can defend.
PLACID instruments are used by acoustics consultancies, university research laboratories, vehicle manufacturers, government agencies, and industrial testing facilities across more than 40 countries. Our engineering team is available for direct technical support and system specification assistance at every stage of your project.
