SVANTEK SV 102A+ Class 1 Dual-Channel Noise Dosimeter
The SV 102A+ is a Class 1 dual-channel noise dosimeter, integrating two distinct functionalities: dual-channel noise measurement and Class 1 frequency range capability. The dual-channel feature allows for simultaneous noise exposure assessment on both sides of the head or in configurations such as underneath a headset and on a shoulder, enhancing the accuracy of noise exposure data in diverse working environments. This capability is particularly beneficial for assessing asymmetric noise exposure, where noise may predominantly come from one direction.
Class 1 accuracy of the SV 102A+ signifies its ability to measure a full frequency range from 20 Hz to 20 kHz. This is a critical feature for workplaces with high-frequency noise sources, as standard Class 2 dosimeters typically measure up to only 8 kHz. The wider frequency range makes sure that the instrument meets the requirements of ISO 9612 for Class 1 instruments, which is important for accurate noise assessment in places where there is a lot of high-frequency noise.
The SV 102A+ also features audio recording, facilitating unattended noise measurements. This capability allows for the playback of recorded noise to identify and verify noise sources, a requirement under ISO 9612 for distinguishing work-related noise from non-work-related noise sources. Additionally, the dosimeter’s 1/1 octave analysis feature enables the precise selection of hearing protectors based on the specific noise environment, further enhancing workplace safety.
The standard SV 102A+ kit includes SV15 preamplifier with cable, SV 7052E microphone, 2x AA batteries, 8 GB memory card and a USB cable for communication with PC. Each SV 102A+ has its factory calibration certificate. The standard kit also includes license for PC software.
