?Accurate measurement?Kereinpo decibel meter uses a precise and durable electret microphone that measures noise levels from 30 to 130 dB with an accuracy of around 1.5 dB and a frequency range of 31.5 to 8,500 Hz. Ideal for monitoring noise levels in neighborhoods, home theaters, sound systems, cars, workshops, schools, offices and factories. ?A/C weighted measurement method?Our Sound decibel meter uses the A/C-weighted measurement method. The A-weighting simulates the frequency of low-intensity human ear noise and has a response speed of 125 milliseconds, which is suitable for the detection of ambient noise. The C-weighting simulates the frequency characteristics of high-intensity noise of the human ear and has a response speed of 1s, which is suitable for the analysis of sound pressure in machine motors and machines. ?LCD Backlit Display?The db meter features a 2.45-inch LCD screen with a large display and four-digit display to ensure clear and easy to read noise level readings. Long press the backlight button to turn on the backlight, even in low light environment can be easily operated and read clearly, improve your detection efficiency. ?Ingenious design?Kereinpo sound level meter adopts the composite injection molding process and has the design of anti-drop structure. At the same time, it is light weight, small size and easy to carry and store. The decibel meter handle is ergonomic and non-slip designed for comfortable grip. The decibel meter has a 1/4 inch mounting thread and can be mounted to a stand for a variety of applications. ?Equipped with batteries?The noise meter is equipped with four durable batteries and has an automatic shut-off function to save energy and prolong battery life. When the batteries are low, a low battery indicator is displayed on the screen to remind you to replace the batteries in time. ?Super Long Standby Testing?Kereinpo decibel meter can work for a long time until the battery power is exhausted. In this way, even if we work half and then leave, there will be no problems. ?USB Data Transfer?Our sound level meter has a USB data transmission function, allowing you to monitor data in real time. You can also save data and download it.
