Noise Decibel Meter, Gedaye Sound Level Meter Range 35-135dBA, SPL Meter with A Weighted, Data Hold Max/Min, Fast/Slow, Color LCD Backlit Display, Noise Detector dB reader Monitor Audio Measure Device

【Sound & Noise Meters】The Gedaye MT-911 decibel meter complies with IEC standards. is ideal for neighbors noise complaints, job-website online and noise pollution monitoring. Perfect for monitoring noise levels in communities, home theaters, audio systems, automobiles, workshops, schools, offices, factories.
【Wide Ranges, High Accurate】Gedaye MT-911 decibel meter is routinely calibrated each and every time it’s turned on. The Noise Meter features a high-sensitivity, high-precision condenser microphone, capable of measuring noise levels from 35 to 135 dB, high accuracy of ±2.0 dB, frequency from 31.5Hz to 8KHz.
【A Weighted, Fast/Slow Measurement】 This SPL accommodates A-weighting and Time-weighting. A-weighting is to simulate the frequency of low-intensity human ear noise, is it more accurate and professional for the detection of environmental noise. The Fast response rate is 125ms for general environmental measurements. Slow response rate of 1s for environmental measurements with rather large variations in noise levels.
【Date Hold, Max/Min Value Measurement】The sound pressure level meter has a Max/Min measurement value, which indicates the High/Low peak value of the sound produced over a certain time period. The Data Hold function freezes the current reading on top of the sound measurement in step with individual needs.
【 Temperature Measurements, Colorful Backlit Display】The MT-911 noise meter accommodates thermometer fuction, range from -4℉ to 158 ℉, accuracy ±2.7℉. It is colorful LCD digital screen with backlight, You’ll be able to easily read even if you find yourself at night or in sunlight.
