Portable Microphone Calibration Kits

Mid-Range Calibration Coupler | K9000 Series

cal microphone k9000 series kitsMicrophone Comparison Calibrator Kits, K9000 Series, include the essential components for calibrating the most popular condenser and array microphones used in Test & Measurement applications. While the Microphone Comparison Calibrator Model 9917C is an established, reliable IEC 61094-5 microphone calibrator, the K9000 Series adds the convenience of SmartSineTM Calibration Driver Model 9000A as a data acquisition system with automation and reporting capabilities. K9000 Kits also include a reference microphone and cabling – just bring your ICP® (IEPE) measurement microphone as a Unit Under Test (UUT).

 The K9000 Series is available in two configurations, offering a choice between a ½" and ¼" reference microphone, Models K9000-917- 1/2 and K9000-917-1/4 respectively. In either case, the reference microphone and UUT are inserted into the acoustic ports of the 9917C. The UUT may be either ½" or ¼" – as mounting adaptors are included. The microphones and the 9917C input connector are connected to the 9000A.

The 9000A maintains a record of the reference microphone calibration values and applies them to calculate the UUT sensitivity during the calibration. Both channels feature ICP® (IEPE) inputs for common microphone signal conditioning. In addition, users can save up to 500 calibration records directly to the unit’s internal memory. Records are transferable via the unit’s USB port to a flash drive and imported as an Excel® spreadsheet, allowing the creation of ISO 17025-compliant customizable calibration certificates on a computer.
