Musktool-MP231 1/2-inch Free-field Microphone IEC61672 Class 1 frequency range 3 Hz ~ 20 kHz
| MP231 is the 1/2-inch free-field microphone developed by BSWA. It is suitable for measurement in free-field and semi free-field environments with minimal sound reflection. It is prepolarized microphone without external polarization voltage, and suitable for ICCP powered MA231 preamplifier (optional TEDS). |
| MP231 is rear-vented and can measure the sound pressure level up to 146 dB in the frequency range of 3 Hz ~ 20 kHz. |
| MP231 is suitable for high-precision universal acoustic measurement and can also be used with sound level meters. |
| MP231 can choose a preamplifier with TEDS to support data acquisition equipment to read microphone information directly, including microphone model, serial number, sensitivity, etc. BSWA microphone supports the IEEE 1451.4 standard. The v0.9 version is used by default to be compatible with more data acquisition equipment. The v1.0 version can also be selected according to user’s requirements. |
| Each MP231 is supplied with an individual calibration data chart including sensitivity, frequency response and so on. |
