A Class 2 Sound Level Meter, also known as Type 2 Sound Level Meter, is designed to meet the IEC 61672-1:2013 standard, ensuring precision and accuracy in sound measurements. Class 2 meters are used for a wide range of applications, offering accuracy specifications for frequencies between 20 Hz to 8 kHz and an operating temperature range from 0 to 40°C. These meters include microphones, preamplifiers, and signal processors that capture and process noise levels, which are then displayed on an integrated screen for easy analysis. Features: Class 2 Sound Level Meter Accuracy Frequency Range: 20 Hz to 10 kHz with linearity deviations of ±1.1 dB. Dual Measurement Ranges: Sound Level Meter: 30 dBA RMS to 129 dBA Peak (according to IEC 61672). Sound Exposure Meter: 45 dBA RMS to 141 dBA Peak (according to IEC 61672). Versatile Applications: Suitable for workplace and environmental noise monitoring, and building acoustics. Reverberation Time Measurements (RT60) Class 2 Accuracy: RT60 measurements for schools or other acoustic applications. Recommended RT60 for Classrooms: Up to 0.6 seconds for rooms < 566 m³ and 0.7 seconds for larger rooms, based on Acoustical Society of America guidelines. Microphone Technology MEMS Microphone: Shock-resistant and energy-efficient, with a 38-hour battery life. Noise Frequency Analysis 1/1 & 1/3 Octave Band Analysis: Precise identification of noise sources for effective noise control and hearing protection selection. WAV Recording: Useful for unattended noise source identification and enhancing sound time history with actual noise samples. Recorded WAV files can be post-processed for sound engineering analysis. |
