Norsonic innovates sound level meters by using a 4.3” large true color touchscreen, to serve you user-friendliness that we know from our smartphones. Further features of the Nor145 is a 3G/4G LTE modem, GPS, an internal web server for remote instrument control on any device (smartphone, pad or PC), and an advanced voice and text note editor. Even photos and voice notes that you make on your phone will seamless be transferred and integrated with markers to your noise data, by installing the NorRemote app (android store).

All these features do make the Nor145 the perfect toolbox for in-situ field measurements.
