No more tedious calibration work with TEDS support! Measurement microphones MI series.
The "MI-1271M12" consists of a free-field type 1/2-inch electret condenser microphone that complies with IEC 61094-4 Type WS2F and a preamplifier. By adopting a titanium diaphragm for the microphone and improving electret performance, it achieves long-term stability and a wide frequency range from 1Hz to 20kHz. It can also be used in a wide temperature range from -30°C to +80°C. When connected to TEDS-compatible equipment, information such as sensitivity is automatically read, eliminating the need for cumbersome calibration work, enabling reliable measurements and time savings. 【Features】 ■ No need for cumbersome calibration work with TEDS compatibility ■ Achieves long-term stability and a wide frequency range from 1Hz to 20kHz ■ Usable in a wide temperature range from -30°C to +80°C ■ Can be directly connected using a BNC cable to equipment equipped with CCLD (constant current drive) power supply *For more details, please refer to the PDF document or feel free to contact us.
