Sound Level Meter, can be Used in Homes, Factories and Streets., 30dB to 130dB, LCD Display, CURCONSA Noise Meter Tester, Portable Decibel MeterCURCONSA
- More professional measurement methods provide users with a more perfect user experience. 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. 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. The slow response rate uses a 1 second time constant, which is used for environmental measurements with relatively large changes in noise levels.
Widely used a sound level meter is an instrument used to measure ambient sound levels. When the battery is low, indicating that the power is low at this point and the battery needs to be replaced.
Large backlit lcd digital display, the LCD display will display a low voltage icon, the reading effect is clearer in dark places. The fast response rate uses a time constant of 125 milliseconds for general environmental measurement. Lcd screen the digital display is a 4-digit lcd display with a resolution of 01 db. It can be used in homes, hospitals, laboratories, schools, residential areas, streets, factories, theaters and sound systems, workshops, offices, hotels, the scope of application is very wide and an indispensable tool in life.

Morza 360 Degrees Rotary Encoder Module Replacement for Arduino Brick Sensor Switch Development Board KY-040 Diy ElectronicMorza
- The rotary encoder can count the number of pulse output during rotation in the positive direction and reverse direction through the rotation and this rotation counts are not limited.
With the key on the rotary encoder, you can reset to the initial state, that is, counting from 0. The rotary encoder can count the number of pulse output during rotation in the positive direction and reverse direction through the rotation and this rotation counts are not limited.
How it works: incremental encoder is a displacement of the rotary pulse signal is converted to a series of digital rotary sensors. 360 degrees rotary encoder module is a great replacement for the old one, providing stable performance.
