Decibel Meter, CURCONSA Sound Level Meter, Portable SPL Meter, 30dB to 130dB, LCD Display, can be Used in Homes, Factories and Streets.
The noise standard is to maintain human well-being and living environment and limit the allowable range of noise. Formulating principles: It should be based on protecting people’s hearing, sleep and rest, talking and thinking, and should be advanced, scientific and realistic. Strong noise will have adverse effects on human physiology and psychology. In daily life and living environment, noise can cause hearing loss, pre-disturbing conversation, thinking, and sleep. CURCONSA sound level meter has the characteristics of simple operation, simple operation, large dynamic range, large-screen LCD digital display, and automatic measurement. It can be widely used for industrial noise measurement and environmental noise measurement of various machines, vehicles, ships, electrical appliances, etc., and it can be used for acoustic testing in factories and enterprises, construction design, labor hygiene, transportation, teaching, medical and health, scientific research and other departments range. LCD Screen The digital display of the sound level meter is 4 digits, and the screen used is a large backlit LCD screen, which makes the reading effect clearer in the dark Automatic Shut-down To save power, the sound level meter will automatically shut down if there is no operation for 10 minutes Easy to Carry The sound level meter is small in size and light in weight, and can be easily placed in a pocket or backpack for easy portability Read more Keep Maximum Long press the "F/S/MAX" key for 2 seconds to switch to the MAX maximum hold function, and measure the maximum noise in the environment. (Long press again for 2 seconds to exit the MAX hold function) Battery Powered The device is equipped with two 1.5V batteries. If the battery is exhausted, you can open the battery cover screw on the back of the meter, remove the battery cover and replace with a new battery High Precision Noise accuracy: ±2.0dB (reference sound pressure standard, 94dB1KHz) Frequency response: 31.5Hz~8KHz Dynamic range: 50dB Measuring range: 30~130dB Read more Read more
Product Features
- Widely Used A sound level meter is an instrument used to measure ambient sound levels. It can be used in homes, factories, workshops, schools, residential areas, offices, streets, hotels, hospitals, laboratories, theaters and sound systems, the scope of application is very wide and an indispensable tool in life.
- High Precision The measuring range of the sound level meter is 30dB to 130dB with fast response speed and stable and reliable performance. This product is a high-precision noise meter with an accuracy of 2.0 dB. Real-time monitoring can give you accurate data on the sound level in the area.
- A / C Double-weighting Measurement The A-weighting simulates the frequency characteristics of low-intensity human ear noise, which is suitable for the detection of ambient noise. The C-weighting simulates the frequency properties of high-intensity noises of the human ear, which are suitable for the sound pressure analysis of machine motors and machines. More professional measurement methods provide users with a more perfect user experience.
- Fast and Slow Response Rate Conversion The sound level meter has the function of converting the fast and slow response rate. The fast response rate uses a time constant of 125 milliseconds for general environmental measurement. The slow response rate uses a 1 second time constant, which is used for environmental measurements with relatively large changes in noise levels.
- LCD Screen The digital display is a 4-digit LCD display with a resolution of 0.1 dB. Large backlit LCD digital display, the reading effect is clearer in dark places. When the battery is low, the LCD display will display a low voltage icon, indicating that the power is low at this point and the battery needs to be replaced.
