The Pulsar Model 45 Class 1 decibel meter is an extremely accurate, reliable, ‘handheld’ precision instrument that is especially suited to measuring noise pollution. It successfully combines the latest technology in noise measurement methods with ease of use and durability. It can also be used for measuring noise across many different applications: noise at work, construction, entertainment, environment and for measuring machinery and vehicle noise.

The Model 45 is an ideal instrument for precision occupational noise measurement to ensure compliance with International Occupational Noise or Industrial Hygiene Noise Directives to be used as part of a company Health and Safety strategy. This model includes real-time 1:1 Octave band filters for the prescription of correct levels of hearing protection.

The added features of this class 1 decibel meter include Audio Recording, Ln Values and Data logging.
