Decibel Meter, Gedaye ET-933 Sound Level Meter, Range 30-130dBA(C), SPL Meter with A/C Weighted, 3.5" Backlit LCD Display, Data Hold Fast/Slow, Max/Min, Audio Measure Device Sound Detector dB Reader
【A/C Weighted Measurement】The SPL meter contains specialized A and C weighting technology. A Weighted to simulate the frequency of low intensity human ear noise, suitable for detecting environmental noise. C-weighting is suitable for high-frequency and high-intensity noise measurements, such as sound pressure analyses of machine motors and machinery. More professional technology makes the measurement data more accurate.
【FAST/SLOW Measurement】The ET-933 sound level meter fast response rate is 125ms/time for general environmental measurements. Slow response rate of 1s/time for environmental measurements with relatively large variations in noise levels.
【DATE HOLD, MAX/MIN Measurement】The sound pressure level meter has a Max/Min measurement value, which indicates the Max/Min (High/Low peak) value of the sound produced over a certain period of time. The Data Hold Function freezes the current reading on the screen (values change quickly when FAST measurement state). Convenient for recording the measured values.
【3.5 inch LCD Screen with Backlight】The ET-933 Sound Level Meter measures noise levels in decibels (dB). Displayed on a 3.5" LCD screen with backlight. Press the power button to turn on the backlight, you can easily read even when you are at night or in sunlight.
