Digital Sound Level Meter can easily test and read the noise level from 35`140dB(A), Summary:HS5633 digital sound level meter is newly developed according to the requirements of the new standard of national sound meter, it has A, C sound levels, and with functions such as Max. maintenance, sound level set, high and low range, digital display of overload and oweload, AC and DC signal output, etc., suitable for measuring environmental noise, traffic noise, mechanical noise, electric noise, etc., also, it can be used on measurement of architecture acoustics, electroacoustical, etc. This instrument has stable performance, is convenient to use, with advantages such as compact structure, small cubage and light weight, especially suitable for on-the-spot measurement of various noises. It accords with the requirements of IEC61627 <Sound Level Meter> standard to Model 2 sound level.Main technical index and function:1. Measuring range of sound level meter:35130dB(A;2. Frequency range: 20Hz12.5kHz;3. Frequency-weighted features: AC weighting ;4. Sound level set function: random set within 40130dB;5. Demodulation feature: virtual value;6.
