Digital sound level meter for measuring noise level 30 ~ 130dB SNDWAY SW-523

Product detailed description

Properties:
This DB sound meter complies with IEC651 type 2 and ANSI S1.4 type 2 standards, with a measuring range from 30 to 130 dB and an automatic shift function, selection of frequency weighing mode A and C and high speed (FAST) / low speed (SLOW) selection response rates.
The mini handheld digital sound level reader is compact, light and easy to use, it is not only extremely wear-resistant, but also elegant.
The AC and DC analog signal outputs can be connected to a frequency analyzer or XY axis recorder for statistical data analysis.
Function with backlight function, is suitable for collecting audio data at night. And there is an automatic shut-off function, thanks to high reliability and a well-designed highly efficient power supply circuit, the battery is more durable.
Portable and easy to use, suitable for controlling, monitoring or controlling sound levels for personal, family, business, study, industrial, etc.
