Product Specification unless deselected above

Brand Castle Group
Available Outside the UK? Yes

Most Measurement codes of practice and legislative guides demand that an acoustic ‘field’ calibration of any sound level meter should be made before a series of measurements and that the accuracy is checked afterwards. The Castle dBCal Calibrators provide just that with 3 output levels, long battery-life and highly ergonomic design. Considerable care has gone into making sure that this is the only sound calibrator has its controls and displays on the same ‘line-of-sight’ surface as the sound meter.
