Pulsar Nova Model 41 & 42 Class1/Class 2 Sound Level Meter

The Model 41 & 42 are the entry level meters in the Nova range.

Utilising the latest digital platform of the Nova range along with the large, high resolution colour OLED screen, the 41 & 42 are basic, easy to use Class 1 (Model 41) and Class 2 (Model 42) sound level meters designed to measure general sound level (decibels) in your location/environment.

These meters are the ideal choice where integrated noise levels such as LEQ or L10 are not required, yet the highest accuracy and quality are required as well future up-gradeability.

Data logging, LEQ, Ln values, 1:1 Octave plus a range of other key Nova features can be added to the Nova 41 & 42 either upon purchase or at a later stage.

The Model 41 & 42 can be purchased as meters only or as a full measurement kit incl. calibrators, wind shields, carry cases and tripods.
