- Class 2 Sound Level Meter, also known as Type 2 Sound Level Meter, is a professional noise level meter designed to meet the requirements of the IEC 61672-1:2013 standard for precision and accuracy. The specifications for Class 2 and Class 1 sound level meters share similar design goals, primarily differing in their acceptance limits and operational temperature ranges. The acceptance limits for a Class 2 Sound Level Meter are generally equal to or greater than those of a Class 1 meter, depending on frequency. The accuracy of a Class 2 Sound Level Meter is specified by IEC within a range of 20 Hz to 8 kHz, and a temperature range from 0 to 40°C. As per the IEC 61672 standard, a Class 2 Sound Level Meter is equipped with a microphone, a preamplifier, and a signal processor. These components work in unison to capture and process noise levels, which are then displayed on an integrated screen. This design ensures accurate, reliable results in professional noise level monitoring applications.

- The SV 973A is a Class 2 sound level meter with a wide frequency range up to 10 kHz. A unique feature of the SV 973A is the microphone based on MEMS technology with a lifetime warranty
- The meter is suitable for measurements of noise at work in accordance with standards such as ISO 9612, OSHA, MSHA and ACGIH, and hearing protector selection in accordance with ISO 4869-2.
- The 1/1 octave analysis is often used for the selection of hearing protectors. The 1/3 octave function makes it possible to determine the influence of high or low frequencies on the overall values. The STIPA and RT 60 can be used in applications where it is permissible to use class 2 meters for measuring the speech transmission and reverberation time. These functions can be activated at any time by ordering an activation code.
- Audio recording is synchronised with a noise time-history which can be opened and played back in PC software to enable noise source recognition. Audio recording can be triggered based on a threshold or time. It can be activated at any time by ordering an activation code.
- The time history logging of results such as Leq, Max, Min and Peak with two simultaneous logging steps is saved to 8 GB internal memory
- Using MEMS technology, the new microphone is resistant to mechanical shocks and consumes less energy, which translates into an extremely long battery life, of up to 38 hours!
