Noise Tester Measuring Instrument 30-130dB dB Meter Digital Audio Sound Level Detector Meter Decibel Monitor Feature: Polarized condenser microphones provide good performance for precision noise measurement and capacitance testing. Professional noise measurement, can detect 30dB-130dB noise, 2 kinds of response speed modes are available. Real-time measurement, fast response: The sampling frequency of indoor and outdoor environmental noise has a fast response of 0.125 seconds/time, and a slow response of 1 second/time. A/C dual-weight measurement: A-weight can simulate the frequency characteristics of low-intensity noise of human ears, which is suitable for environmental noise detection; C-weight can simulate the characteristics of high-intensity noise, and is suitable for sound pressure analysis of machine engines. Easy to carry design: exquisite shape design, convenient to put in the pocket, making noise measurement easier. Backlight display: When clear reading/no parallax is activated, the default backlight is always on. During the measurement, press and hold the MAX button for one second to lock the maximum measurement value. Suitable for environmental noise detection/sound insulation detection/industrial noise detection/electrical noise detection, etc.
