Recalibration

Calibration

Even though your new Digital Sound Level Meter comes calibrated to NIST (National Institute of Standards and Technology) standards, over time, its accuracy will begin to decline. It is recommended that your Digital Sound Level Meter should be recalibrated every year. EXAIR is able to perform this recalibration to make sure that your Digital Sound Level Meter is maintained to NIST standards!
