Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•【Wide Ranges, High Accurate】Gedaye ET-973 decibel meter is automatically calibrated every time it is turned on. The Noise Meter features a high-sensitivity, high-precision condenser microphone, capable of measuring noise levels from 30 to 130 dB, high accuracy of ±2.0 dB, frequency from 31.5 Hz to 8K Hz.
•【A/C Weighting, Fast/Slow Measurement】The instrument employs A-frequency weighting for measurements, simulating the human ear's response to sound. This is particularly suitable for assessing the impact of environmental noise on hearing. The fast response rate of 125 milliseconds is appropriate for routine environmental measurements; the slow response rate of 1 second is suitable for measurement scenarios in environments with significant fluctuations in noise levels.
•【Thermometer, Digital LCD Display】The noise meter contains thermometer fuction, range from -4℉ to 140 ℉, accuracy ±1.8℉. It's colorful LCD digital screen with backlight, You can easily read even when you are at night or in sunlight.
•【Date Hold, Max/Min 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 period of time. The data hold function freezes the current reading to facilitate data recording.
•【Extensive Application Scenarios】Gedaye sound level meter complies with IEC standards and is suitable for measuring traffic noise, industrial noise, workshop noise, and the performance of sound systems. It is perfectly suited for monitoring noise levels in communities, home cinemas, vehicles, schools, offices, and factories, providing reliable data support in all these settings.
•【Package Include】1x Sound Level Meter, 3*AA 1.5V LR6 Battery, 1x Instruction Manual, 1x Type-C Cable. (Service: If the product has quality problems, will offers a 1-year free replacement).
