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

Features

• [(SPL Sound Level Meter)] The Gedaye ET-933 decibel meter complies with the IEC61672-1 CLASS2 Standard, supports Manual Calibration. Perfect for monitoring noise levels in communities, neighbors noise, home theaters, audio systems, automobiles, workshops, schools, offices, factories noise pollution.
• [(Higher Accurate, 4 Measurement Range)] Gedaye ET-933 Noise Meter features a high-sensitivity, high-precision condenser microphone. 4 Measuring Range: (Auto: 30dB-130dB, Lo: 30dB-80dB, Med: 50dB-100dB, Hi: 80dB-130dB); Accuracy:+-1.4dB (Frequency 31.5Hz ~ 8KHz ).
• [(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.
• [(After-Sale, Package Include)] 1x ET-933 Decibel Meter, 1x Storage Bag, 1x 9V Batteries, 1x Windproof Cotton Cover, 1x User Manual. (Service: If the product has quality problems, Gedaye will offers a 1-year new replacement).
