Home Portable LCD Digital Display Decibel Detector With Wind-proof Ball Precise Measurement 30dba~130dba Noise Meter |

Features:

1. [Large LCD display and wind-proof ball] Our decibel meter uses a large LCD display, which is easy to identify in a dark environment. The reading is clear and easy to use at night. It is widely used in factories, transportation, automobiles, baby rooms and sound system offices to control sound quality in homes, schools and construction sites. When measuring outdoor noise, you can install the wind-proof ball on the microphone head to prevent the microphone from being blown directly by the wind and wind. Other noises are also measured.

2. [Pre-calibration and min/max/data saving functions] Sound level meter decibel calibration procedure-1. Open the calibrator and set the status to 94 decibels. 2. Open the calibrator and adjust the nameplate in the battery box of the meter until the LCD shows the required level of 94.dB. A correction knob is attached to the rear, and the SPL meter records the minimum and maximum sound decibels. The decibel meter will keep reading until a higher/lower reading is picked up.

3. [Precise measurement and over-range measurement warning sign] Measurement range: Our noise meter can read between 30dBA and 130dBA, while reducing the influence of wind noise and producing more accurate readings. The sound level meter provides readings within +/-1.5dBA, providing some of the most accurate results! In addition, the decibel meter displays "UN" under the range and "OL" on the screen. Sound timing test reading exceeds the standard you set. Noise dosimeter noise measurement

4. [Automatic backlight display and low battery prompt] The light sensor will automatically sense the ambient light intensity: when the light intensity is insufficient, the backlight will automatically turn on. The backlight changes according to the light intensity. When the electronic power of the battery is insufficient, a symbol may appear on the LCD to indicate that the electronic power of the battery is insufficient, and the battery must use a new battery.

5. [Auto-off] When not in use, it will automatically turn off after 11 minutes to save battery life. The noise level meter can be used in most homes/businesses, such as monitoring the noise level of factories, offices, and theaters. Use music recording, neighbor noise complaints, industrial office settings, voice therapy.
