Sound level meter UNI-T UT352 data logging

Sound level meter UNI-T UT352 data logging
The UT 352 sound level meter is a high-quality device for measuring sound levels in environmental control, measurement in healthcare and industry. It contains a sensitive condenser microphone with a frequency range of at least 31.5Hz to 8000Hz. It is possible to choose measurements according to the physiological sensitivity curve of the human ear (A), or the curve for measuring machine noise (C). The range of noise measurement can be switched in four subranges from 30dB to 130dB and it is also possible to select the response speed either fast 125ms or slow 1s. The analog outputs allow the direct output of audio with a voltage level of 0.707V or DC voltage, the magnitude of which varies depending on the magnitude of the noise 10mV / dB (2V at full range). Measured data can be stored in the internal memory (up to 63 measurement sets). Very low power consumption allows continuous measurement for up to 20 hours, but also allows power from an external source. Low battery indication when the voltage drops to 4.8V.
