The sound noise level meter can measure 30~130db noise decibel values, with a dynamic range of 100dB, and three levels of noise levels, which can more accurately measure the ambient sound of Pinghu. It can also measure temperature and humidity, provide a time display, and facilitate users to read data.
Fully Functional
Quality Assurance
A sound level meter is a device used to measure sound intensity. It is widely used in many fields such as environmental monitoring, industrial production, building design and construction, traffic management, occupational health and safety, etc. Measuring the sound intensity in different areas, helps planning departments understand and control urban noise pollution, and also provides data support for traffic planning and noise control. It is used to detect the noise generated by medical equipment during operation to ensure that the noise of medical equipment will not interfere with and harm patients and medical staff. It is used to detect the noise generated by fire-fighting facilities during operation to ensure that the noise of fire-fighting facilities will not interfere with and harm the surrounding environment and personnel. In times of crisis, it can promptly and effectively sound the alarm to guide people to escape.

Q1: What is a noise detector?
A1: Noise tester is an instrument used for noise detection and testing in public places such as work sites and squares. Factory noise monitoring Noise pollution is one of the environmental pollutions that have a greater impact. Higher decibel noise can even cause serious damage to people's eardrums and cause deafness. The application of the noise tester can provide the decibel that the noise reaches in order to take relevant measures to control and reduce the noise. The measurement unit of the sound level is decibels. The professional noise tester has a highly sensitive sensor, high accuracy, and a wide range of applications. It can be widely used for noise measurement in various environments. Sound level measuring instrument, collectively referred to as sound level meter.
Q2: Sound level meter working principle
A2: The sound level meter uses a microphone to convert the sound into an electrical signal, and then a preamplifier converts the impedance to match the microphone with the attenuator. The amplifier adds the output signal to the weighting network, performs frequency weighting on the signal (or an external filter), and then amplifies the signal to a certain amplitude through the attenuator and amplifier, and sends it to the effective value detector (or external press Level recorder), give the value of the noise level on the indicator head.
Q3: How big is the decibel scale?
A3: Sound is measured in decibels (dB). Whispering is about 30 decibels, normal conversation is about 60 decibels, and motorcycle engines run at about 95 decibels. Noise above 70 decibels for long periods of time may begin to damage your hearing. Loud noises above 120 dB can cause immediate damage to your ears.
Tips: How to maintain the accuracy of the sound level meter's measurement results in a noisy environment?
When a sound level meter is in a noisy environment, its measurement results may be interfered with by many factors. First, the environmental noise itself will have a direct impact on the sound level meter's measurement, because the sound level meter will capture these noises and convert them into electrical signals, resulting in deviations in the measurement results. Secondly, other factors such as electromagnetic interference that may exist in a noisy environment may also affect the measurement accuracy of the sound level meter. Therefore, when using a sound level meter for measurement, you should try to choose a relatively quiet and interference-free environment or take appropriate measures to reduce the impact of environmental noise and interference to ensure the accuracy of the measurement results.
