The PLACID Instruments product catalog spans the complete acoustic and vibration measurement signal chain. Every product is specified, manufactured, and calibrated to work as part of a coherent, traceable measurement system. Whether you are building a new measurement infrastructure from scratch or replacing individual components in an existing setup, you will find calibrated instruments backed by documented uncertainty values and direct technical support.
PLACID products are used in environmental noise monitoring programmes, automotive NVH test facilities, university acoustics laboratories, industrial compliance testing, and building acoustics consultancies. Our catalog is focused on performance-appropriate instruments — every specification is meaningful, every calibration certificate is traceable.
Class 1 and Class 2 condenser measurement microphones in 1/2-inch and 1/4-inch sizes. IEC 61094-4 compliant working standard microphones for free-field, pressure-field, and random-incidence applications. Self-noise as low as 10 dB(A), frequency range to 40 kHz, dynamic range exceeding 140 dB SPL. TEDS-enabled variants available for automatic instrument identification in multi-channel systems.
Matched microphone and preamplifier sets provide a complete, tested, factory-calibrated measurement chain ready for immediate deployment. IEPE and voltage-mode preamplifiers with low self-noise and wide bandwidth from 3 Hz to 100 kHz. Compact preamplifier bodies for close-coupling to the capsule to minimise cable capacitance effects.
4, 8, and 16-channel simultaneous sampling DAQ systems with 24-bit ADC resolution and selectable IEPE current supply on all channels. USB and Ethernet connectivity. Compatible with PLACID PQ Analyst software and open Python, C#, C++, and MATLAB SDKs.
