The Model 41 Nova Class 1 Sound Pressure Level Meter (SPL meter) is the perfect choice where high-accuracy but basic noise data, Time and Frequency Weightings are all that is needed for your sound level assessments. The meter measures all these noise parameters simultaneously and displays them on its high-resolution OLED screen.

This is an ideal instrument for basic noise at work measurements, as with all the meters in the Nova range, the Model 41 is compliant with International Occupational Noise or Industrial Hygiene Noise Directives and can be used as part of a company Health and Safety strategy.

This SPL meter has been designed to be easy to use whilst providing the user with the fundamental parameters required to comply with current legislation. It can be upgraded to become a data logging meter or by adding further options as shown in the comparison table (below) to make it into a versatile instrument.

The Nova Range consists of six powerful sound level meters. These differ from other sound level meters, as they offer you the unique opportunity to add features either immediately or at a later date so that your sound level meter will always be suitable for your requirements.
