The SVAN 977A is a Class 1 Sound and Vibration meter designed for occupational and environmental measurement applications. The SVAN 977A is a successor of SVAN 977 offering bigger memory 8 GB and the Bluetooth® interface as a software option that can be enabled at any time. The meter provides broad-band results such as Leq, Max, Min and Peak with all standard weighting filters together with an incredible time-history logging feature with two adjustable logging steps.
One unique feature of the SVAN 977A is ultrasound measurement band up to 40 kHz. The ultrasound band is normally considered as the frequency range above 20 kHz. Ultrasound is used in a number of industrial processes such as cleaning, drilling or welding as well as hospitals for medical procedures.
The built-in Bluetooth® interface together with smart-phone application, SvanMobile, extends measurement capabilities with all the features offered by smartphones including text/voice comments, photo, video, GPS position etc.

With the option of time signal recording SVAN 977A can record the raw signal samples with defined frequency up to 48 kHz. Analysis of the raw signal is used whenever frequency analysis is not sufficient. Post-processing of high quality wave files (48 kHz, 24 bit) such as calculation of tonality is available in SvanPC++ program. Time signal is recorded in a wave format which means that it can be played back in the PC software and used for noise source recognition (audio recording).

The SVAN 977A kit consists of SVAN ??977A Class 1 sound & vibration level meter with a detachable preamplifier SV 12L and high quality omni-directional SV? 7052E microphone, compliant to IEC61094-4. The list of accessories includes: SA 143 carrying case, SA ?22 windscreen, 8 GB microSD card, four AA batteries, USB cable, and CD with user manual. Each SVAN? ???977A has its factory calibration certificate and 36 months warranty card.

With an optional microphone and 1/3 octave or FFT analysis SVAN?? ?977A provides analysis of the ultrasounds up to 40 kHz. The ultrasound band is normally considered as the frequency range above 20 kHz. Limits of permissible ultrasound levels are usually expressed in terms of Leq and Max values specified in 1/3 octave bands for 20 kHz, 25 kHz, 31.5 kHz and 40 kHz.
