Review on 🎧 Enhance Sound Accuracy with Extech 407744 Sound Calibrator Microphones by Bobby Martinez

I need a calibration certificate for this calibrator please reply me

I need a certificate for this calibrator. I first bought this product to calibrate my Extech HD600 but I have found that this product does not come with a calibration certificate which I must provide for the project without which it is useless.
