 The software of the Acoustilyzer and Minilyzer have been optimised for acoustical analysis when used in conjunction with the MiniSPL. For more information visit www.nti-audio.com Please Note: Whilst the Minstruments range is calibrated at the factory, they are not supplied with a calibration certificate as standard. If you require a full 12 months certificate, the unit will be ordered from the NTI factory and not supplied from stock. |
