The Nova sound level meter can be used to make instantaneous sound level measurements, or it can be fitted with the data logging option for longer term measurements.
As a hand-held meter, it measures the current sound level with Fast, Slow and Impulse time weightings, as defined in the ANSI S1.4 and IEC 61672 sound level meter standards. It also measures with A, C and Z frequency weighting.
As all time and frequency weightings are carried out simultaneously in the meter, there is no pre-measurement setup to go through, just press Start and the measurement begins.
The Nova Model 41 (Type 1) and Model 42 (Type 2) are for noise surveys that demand a professional grade meter that is quick and easy to use.
