• 【5 in 1 Decibel Meter】This decibel meter has an 8.6 inch high-definition LCD screen with adjustable brightness and a decibel meter, which means you will have a noise meter+thermometer+hygrometer+clock+time.The A-weighted SPL meter simulates the frequency characteristics of low-intensity human ear noise, which is suitable for the detection of ambient noise.
• 【High Accuracy Measuring 】The sound level meter measures range from 30 – 130 dB with an accuracy of ±1.5 dB, Frequency from 35 to 8.5KHz,Humidity range: 20~85%,Temperature Range : -10°C - 60°C (14℉-140℉) Due to the different environments, the actual measurement value has a deviation of 0~15% which is a normal range.
• 【Charge-Friendly】This decibel meter built-in 2000mAh lithium battery power supply, comes,Endurance time of 3~5 days, ultra-long standby only need to charge once a week.The decibel meter can be used in many environments and is also suitable for noise engineering, product quality control, health prevention, treatment, etc.
• 【Note】The product is calibrated and tested and sent out, it will consume a certain amount of power,So generally out-of-the-box batteries are in a non-full state.The battery level indicator shows red when charging and green when full.
• 【Easy to Use】Click "left button" to enhance the brightness, click "right button" to reduce the brightness,Long-press "M" to adjust the time.We prefer to use Portable Decibel Meter on the countertop.
