The Pulsar Model 42 Nova Sound Level Meter (Class 2) is the ideal choice where integrated noise levels, such as Leq and Peak are not required and where basic noise data such as Sound Level Pressure (SPL) or Time and Frequency Weightings are all that is needed.

The display used on the Nova® is a high resolution colour OLED type. This gives a clear, bright display that is easy to read in all light conditions as well as allowing us to use colour to show specific functions and information. All the information that you need is shown clearly on the screen with the most useful function, for example the Leq in the Leq View, shown in large text. This makes it easy for you to see the information that is important at a glance.


Ideal for basic noise level assessments, emergency service alarm testing, sound system installation and vehicle noise measurement.
High resolution anti-glare, large full colour OLED (organic light-emitting diode) display.
Illuminated keypad, ambient light sensor.
Complies with IEC 61672-1:2013, IEC 60651:2001, IEC 60804:2000, IEC 61252:1993.
