TA0505 - 1/2" Input Adapter (20 pF)

In acoustic measurements (SPL, frequency response, noise, reverberation, etc.), large errors often come not from instrument accuracy, but from a mismatch between the assumed sound field and the actual one. What a microphone reads as sound pressure is not strictly equivalent across different fields-especially at mid and high frequencies, where the microphone dimensions become comparable [...]

Measurement microphones are used in acoustic metrology, type-approval testing, and engineering measurements. Unlike general audio capture applications, measurement scenarios place far greater emphasis on consistency and traceability: the same microphone should deliver stable output when re-tested over time; variation within a production lot should be sufficiently small; and performance fluctuations between lots should remain controllable. [...]

As the core component of measurement chains, the long-term stability of measuring microphones directly impacts the comparability and traceability of measurement data. The 10-year limited warranty (hereinafter referred to as the 10-year warranty) is not merely a service commitment, but a comprehensive capability demonstrated through manufacturing consistency control, reliability verification systems, and traceable evidence chains.
