Relatively Fast Response
■ 1/2 inch free sound field type BNC Microphone Long-term stability, operation at -50 ° C to 125 ° C The best -selling micro hon that has been developing the most long -term measurement microphones in the world. A free sound field -type microphone with a BNC connection boasts an amazing stability of less than 1 DB even after 1,000 years (20 ° C, estimated value in dry state). Designed for high -sensitivity, wide dynamic range and high -precision measurement within the temperature range. ■ Examples of use ・ It is a free sound field type for electrical sound measurement such as vehicle speakers, smart speakers, and infotainment system tests, and frequency response is designed flat. ・ It can be continuously operated up to 125 ° C (257 ℉) for measurement at high temperatures near the motor. ・ IEC 61094-4 WS2F type 1 free sound field microphones for measuring the sound power of washing machines, horticultural tools, machinery, medical devices, etc., ideal for acoustic power measurement. -The airplane, automobiles, trains, etc. external noise is measured, and the frequency response is designed on a free sound field type in the infotainment system in the vehicle. -The wide dynamic range, wide frequency range, and wide operating temperature range for general -purpose measurement correspond to any measurement.
