These specifications are for the Pulsar Nova Model 45 and Nova Model 46 Integrating Sound Level Meter.
Most occupational noise regulations demand the use of a Type 2 Sound Level Meter. Both the Model 45 and Model 46 meet or exceed these requirements. Note that you should also have a suitable Sound Level Calibrator.
If you have any questions about the standards your meter needs to meet then please call on +44 845 680 0313 or email on firstname.lastname@example.org.
