Polarized capacitor microphone provide performance for precision noise measurement apacitive test.
It is the professional noise measurement which can detect 30dB~130dB noise and with 2 response speed mode for you to choose.
Real-time measurement and quick response: Indoor and outdoor environmental noise sampling frequency quick response is 0.125 seconds/time and slow response is 1 second/time.
A/C dual weight measurement: A weighting can simulate the frequency characteristics of low-intensity noise of the human ear, suitable for environmental noise detection, and C weighting Simulate the characteristics of high-intensity noise, suitable Sound pressure analysisof machine engines.
Easy to carry design: Exquisite shape design easy to fit in your pocket Make noise measurement easier.
Backlight display: The default backlight is long on when starting up Clear reading/no parallax.
Long press the MAX button for second during measurement Lock the maximum measured value.
Suitable for environmental sound detection sound insulation detection/ industrial noise detection Sound detection such as electrical sound detection.
