Pursuing the precision of acoustic measurement. The MI series measurement microphones from Ono Sokki achieve both high sensitivity and wide bandwidth.
Improvement of automotive quietness, abnormal noise inspection of home appliances, vibration analysis of precision instruments. High-precision sensors that do not miss subtle air vibrations are essential for "accurate acoustic measurements" required in manufacturing sites. 【Features】 The MI series from Ono Sokki is a measurement microphone with a wide lineup ranging from the industry-standard 1/2 inch to ultra-high frequency compatible 1/4 inch. ● High sensitivity and low noise design: Achieves accurate data collection without distortion, from faint sounds to high sound pressure. ● Excellent environmental resistance: Maintains minimal sensitivity changes even in harsh field environments, ensuring reliability for long-term measurements. ● Easy setup: The preamplifier integrated model compatible with BNC connectors allows for smooth connection to acoustic analyzers (FFT analyzers). You can choose the MI series according to your application, from research and development to inline inspection. The MI series visualizes sound and strongly supports the improvement of product quality and reduction of development time for our customers, providing a solution for acoustic measurement.

basic information
【MI-1271】 This is a precision-grade 1/2 inch back electret microphone. By adopting a laser-welded fixation method for the titanium diaphragm, it achieves extremely high stability. Additionally, it features a wide temperature and humidity range (-30 °C to 80 °C / 0 to 90 %RH) and a broad frequency range (1 Hz to 20 kHz), making it a high-performance microphone capable of meeting various applications such as environmental noise measurement in high temperature and humidity environments, measurement of ultra-low frequency sounds (up to 20 Hz), and sound measurement during cold start tests of automobiles. 【MI-3170】 This is a preamplifier for 1/2 inch back electret condenser microphones, which can be used in combination with the MI-1271 microphone. With the adoption of the CCLD (constant current drive) method and BNC connector, it can be directly connected to many CCLD-compatible amplifiers and analysis equipment. When combined with the MI-1271, it covers the measurement range of ultra-low frequencies starting from 1 Hz and achieves a wide operating temperature range (-30 °C to 80 °C). *For more details, please refer to the PDF document or feel free to contact us.*
