CRY3261-S01 Free-Field Microphone Set, 1/2″, 354mV/Pa
CRY3261-S01 is a 1/2-inch free-field prepolarized measurement microphone and preamplifier set widely used in acoustic testing environments such as anechoic chambers and quiet rooms.
The unique design of CRY3261-S01 allows it to have an extremely low self-noise, making it highly suitable for detecting and measuring ultra-low noise levels. Typical applications include measuring the self-noise of products, computer fan noise, transformer current noise, and evaluating environmental noise.
