The Nor103 offers a compact and ergonomic design for portable and convenient noise measurements in any environment.
The Nor103 is a Class 1 Sound Level Meter built for straightforward noise measurement tasks. With a compact and ergonomic design, it’s ideal for handheld use in most environments. Each Nor103 unit includes a pre-polarized condenser microphone, windscreen, rubber protective case, printed manual, and 3-year warranty.
The Nor103 can measure a range of acoustic parameters, including Equivalent Continuous Sound Level (Leq), Fast or Slow time-weighted Sound Pressure Level (Lp), Maximum Sound Level (Lmax), Sound Exposure Level (LE), and Peak Sound Level (LCpeak). The Nor103 supports user-defined A or C frequency weighting and can store up to 199 measurements in its internal memory.
The Nor103 includes the Nor103 sound level meter, pre-polarized condenser microphone, windscreen, rubber protective case, printed manual, and a 3-year warranty.
In addition to the sound level meter, pre-polarized condenser microphone, windscreen, rubber protective case, printed manual, and a 3-year warranty, the Nor103 Option Kit also includes a Nor1255 acoustic calibrator and a small carrying case with room for both the Nor103 and Nor1255.
