High recognition for sound level meter

Pulsar Instruments’ top of the range Nova 45 Class 1 integrating sound level meter has received regulatory type approval from the Physikalisch- Technische Bundesanstalt (PTB). PTB is the highest federal authority and research institute for science and technology in Germany and a recognised authority around the world in the verification of correct and reliable measurements. 

High recognition for sound level meter

Having passed a series of gruelling tests, the Pulsar Nova 45 sound level meter was awarded its certificate and now belongs to an exclusive club of just a few meters officially recognised for their high accuracy against international standards.  This is a tremendous recognition for a product that was launched only a few years ago.  

Pulsar Nova has enjoyed, in recent years, strong commercial success around the world and is the instrument of choice for professionals who are serious about health and safety compliance. It provides users with all the key parameters required under the legislation for noise at work measurements. The meter is also extremely versatile and easy to use. It is suitable for basic, but also advanced noise surveys, depending on the application, with the option of 1:1 octave band filters, Single and repeat timer, TWA/ noise dose and Ln Values as well as the calculation and prescription of hearing protection.

PTB recognition is useful to any safety professionals who value precision, reliability and quality when undertaking acoustic testing in the work environment.  It will be of particular interest for government agencies and bodies, laboratories or noise consultants who, by law, require type approval such as provided by the PTB to support the accuracy of their noise measurements in complex legal cases.

Sarah Brack, MD of Pulsar Instruments, said:  “We are delighted that our Nova Model 45 has been recognised officially by such a prestigious and respected laboratory. At a time when the market is awash with so many meters, it is reassuring for our customers to know that they are offered an instrument that has undergone stringent independent laboratory tests, before they embark on any noise monitoring”.
