MicW CA114 Professional Calibration Device for i436, i437L, M215 & M416 Microphone

Are you in search of a reliable, compact sound source for the calibration of your measurement microphones, sound level meters, and other sound measuring equipment Look no further than the BSWA CA114 Professional Calibration Device. Specifically designed for i436, i437L, M215 & M416 microphones, this device is a must-have for professionals seeking precision and accuracy in their sound measurements.

The CA114 is a battery-operated sound calibrator that offers quick and direct calibration of sound level meters and other sound measuring systems. It is compatible with both 1/2-inch and 1/4-inch microphones, the latter requiring an adapter for use.

This professional calibration device conforms to international standards including IEC 60942:2003 Class 2, ANSI S1.40-1984, and GB/T 15173-1994 Class 2, ensuring its reliability and accuracy. The calibration frequency is set at 1000Hz, the reference frequency for standardized international weighting networks. This makes the CA114 suitable for calibrating sound equipment with A, B, C, D weighting filters and linear.

The CA114 is designed to deliver a calibration pressure of 94 +/-0.3 dB (10Pa), providing a highly stable sound pressure level. This is achieved through a feed-back arrangement that includes a reference microphone, a sound source, and a control circuit. The reference microphone has undergone a rigorous long-term aging test, ensuring its stability and reliability.

The feed-back control circuit adjusts for changes in load volume, temperature, humidity, and atmospheric pressure, ensuring consistent performance under varying conditions. The device also features an automatic switch-off mechanism when the microphone is removed from the cavity, extending the battery life.

The CA114 is also equipped with a low battery indicator. When the ON/OFF light flashes, it indicates that the battery voltage is low and needs replacement.

In summary, the BSWA CA114 Professional Calibration Device is a compact, reliable, and versatile tool for professionals in the field of sound measurement and calibration.
