Description
UNI-T UT352 Data-Logging Sound Level Meter
This product comes with a 3-year warranty. The UT 352 sound level meter is a high-quality device for measuring sound levels in environmental monitoring, healthcare and industrial applications. It features a sensitive condenser microphone with a frequency range of at least 31.5 Hz to 8000 Hz. You can choose to take measurements based on the physiological sensitivity curve of the human ear (A) or the machine noise measurement curve (C). The noise measurement range can be switched between four sub-ranges from 30 dB to 130 dB, and it is also possible to select either a fast response time of 125 ms or a slow response time of 1 s. The analogue outputs allow direct sound output with a voltage level of 0.707 V or DC voltage, the magnitude of which varies in proportion to the noise level at 10 mV/dB (2 V over the full range). Measured data can be stored in the internal memory (up to 63 measurement sets). Very low power consumption allows for continuous measurement for up to 20 hours, but also allows for power supply from an external source. Low battery indication when the voltage drops to 4.8 V.
