Production line testing ensures that finished products match the target quality set by R&D and that no sub-standard units hit the market.
Production line microphones must provide repeatable and precise measurements every day to ensure that products that do not meet specifications are not delivered to the end users, and as they are often needed in greater numbers than in R&D labs, they must also fit your budget. GRAS production line microphones provide the best combination of cost and quality.
Freq range: 20 Hz to 20 kHz
Dyn range: 30 dB(A) to 120 dB
Sensitivity: 25 mV/Pa
GRAS 40PM EQset™ Miniature Production Line Microphone
GRAS 40PM EQset™ is a short 20 kHz ¼″ pressure microphone with a dynamic range from 30 dB (A) to 120 dB SPL (<3% THD) and the same length (34 mm) as traditional production line microphones. Its fixed sensitivity, flat response curve across all frequencies, and high environmental stability make GRAS 40PM the ideal production line microphone. Learn more about the EQset Technology >>
