Review on 🎛️ Enhanced Precision with the Instruments R8090 Calibrator Diameter Microphones by John Brazington

If you care about using a calibrated sound level meter, you need one of these. There are no whistles or bells in the device. It has a switch that allows you to set the unit to 94dB or 114dB at 1kHz. For more see reedinstruments.com under the heading; Security > Sound Level Meter. The device is used to calibrate sound level meters with a microphone rod with a diameter of 1/2 inch. I believe this is the cheapest calibrator I could find since all other calibrators were in the $250 range. gave it five stars because it works and is available at the best price with shipping I could find and that was after a few days of surfing the web.I can recommend this product for these two reasons and based on personal experience, er does what it is.
