SVAN 971 Class 1 Sound Level Meter is an extremely small instrument with options for 1/1 & 1/3 octave analysis and audio recording. The instrument brings unprecedented state of the art technology to a SLM of this size.
The user interface makes both configuration and measurement easier than ever before. For those who don’t have time to work with measurement settings, SVAN 971 offers extremely simple operational mode with Start/Stop.
This innovation makes the SVAN 971 an ideal choice for many applications including industrial hygiene noise, short term environmental noise, acoustic consultants, technical engineers and general noise measurements.
The successor to the iconic 971 is the new SV 971A class 1 sound level meter with a built-in Bluetooth module for mobile applications.
We are pleased to announce that the SVANTEK SV 977D Class 1 Sound Level Meter has officially received type approval from the Physikalisch-Technische Bundesanstalt (PTB) in Germany.
PTB certification is one of the most prestigious and internationally recognized validations of measurement accuracy and compliance. By meeting the stringent requirements of IEC 61672-1, the SV 977D has demonstrated superior performance in terms of frequency response, dynamic range, directional characteristics, and stability under varying environmental conditions.
Why This Matters
Confidence for Professionals
For acoustic consultants, environmental agencies, health and safety professionals, and researchers, this certification provides peace of mind that the SV 977D is ready for the most demanding and regulated applications. The PTB approval further strengthens SVANTEK’s reputation for delivering high-quality, reliable measurement solutions.
We are pleased to announce that the SV 971A Sound Level Meter has received a positive recommendation from the Central Office of Measures (GUM) and has been granted Type Approval. This marks a significant milestone in the certification process for measuring instruments, confirming that our meter meets the technical and metrological requirements set forth by national regulations and international standards such as IEC 61672.
The type approval procedure includes verifying:
Receiving this positive approval means that the SV 971A is now fully authorized for legal use in applications requiring metrological compliance, enhancing its credibility and quality in the industry.
We are proud of this achievement and invite you to learn more about the SV 971A
As part of the Wireless Acoustics experiment, SVANTEK will send our instruments to the International Space Station (ISS)!
To mark this incredible milestone, we have our very own mission patch—a symbol of our contribution to space research. The design elements reflect our expertise in acoustic measurements and the ISS environment.
