Nor145

Class 1 sound level meter


The advanced Nor145 is our top range sound level meter. Easy to use thanks to its large colour touchscreen and intuitive menus.

It shares the same user interface as Nor150, but hosted in a smaller and lighter enclosure.

Nor145 is a single channel unit optimized for easy connectivity to NorCloud, NorRemote or Nor850, through the built-in WLAN and 3G/4G LTE modem.

Norsonic innovates sound level meters by using a 4.3” large true colour touchscreen, to serve you a user-friendliness that we know from our smartphones. Further features of the Nor145 is a 3G/4G LTE modem, GPS, 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 tool box for in-situ field measurements.
