Description
Type 4971 is a high temperature, CCLD pressure-field microphone set optimized for measurements in 125°C. The microphone is ideal for coupler measurements, random incidence measurements and free-field measurements with 90° incidence.
Being prepolarized, it can be used with CCLD input as well as classical input. It has wide frequency and dynamic range and is highly immune to changing environmental conditions.
- Precision coupler measurements
- Precision-grade sound level meters
- General, random-incidence measurements
- Free-field measurements with 90° incidence
