YUWEN YW-532 Sound Level Meter High Accuracy environment noise measurement instrument

YW-532

Sound Level Meter

YUWEN YW-532 Sound Level Meter provides A/C Frequency Weighting and SLOW/FAST Time Weighting, Measurement range 30~ 130dB, accuracy +/- 1.5dB, suitable for a variety of environment noise measurement needs.

Product Description:

YW-532 is an instrument for measuring environmental noise value, which can be used in machine manufacturing, equipment maintenance,architectural design, transportation, environmental protection and ** and other fields.

YW-532 has a measurement resolution of 0.1dB and an accuracy of ±1.5dB. The instrument supports both A and C frequency metersRight. The low-frequency component of the original noise signal is attenuated by weighting a, which simulates the auditory characteristics of the human earThe size of noise is evaluated from the auditory sense, so it is the most widely used. C Weigh the original noise signal for the environmentThere are fewer modifications to the signal, which can truly reflect the noise level of the environment.

The YW-532 supports both SLOW and FAST timing. Slow time weightingThe time constant is 1 second for measuring steady-state noise: the time constant for fast time weighting is 125 millimetersseconds to measure rapidly changing unstable noise.

The YW-532 also provides a 3.5mm audio interface that can output both DC and AC signals. DC connectionThe port outputs a DC voltage signal, and the voltage is directly proportional to the noise value (10mV/dB), which can be used for dataSecondary calibration or expansion of display devices: AC interface outputs AC voltage signal, which can be used for environmental noiseSpectral analysis of tones.

YW-532X adds a recording function to the YW-532, which can convert the data during the measurement processRecord it all. YW-532X can be used with PC software after connecting to a computer via USB.

YW-532X is equipped with PC software to monitor noise values in real time. Users can view it in the software interfaceThe data recorded by the instrument can also be exported in a variety of different formats using the software.
