Product Details

The Pulsar Nova range of decibel meters combines advanced noise measurement technology with ease of use, practical applications and durability. They are ideal for Workplace Noise, Industrial Hygiene, Construction and Entertainment noise measurement.

The Class 1 Pulsar Nova Model 43 data logging sound level meter is the perfect tool for the Health and Safety Practitioner. Data logging is now included as standard on this Model, which together with our AnalyzerPlus software allows the user to download their measurement data onto a PC or laptop for analysis and to create compliant noise measurement reports in a couple of clicks of the mouse!

This simple to use meter is:

  • Faster. Intuitive design and simultaneous measurement of all key noise measurement parameters means that it's easier to use
  • Stronger. Made with a durable metal case so it is hard-wearing
  • Compliant. Meets IEC 61672-1:2013 and the needs of Noise at Work regulations.
  • Longer. 30-hour battery life so you stay productive
  • Ideal for Workplace Noise, Industrial Hygiene, Construction and Entertainment noise measurement.

The Nova Range consists of six powerful sound level meters. These differ from other noise monitoring equipment, 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. Compare the different Pulsar Nova Models within the range.
