Product Features
- Compact and portable: as small as a ballpoint pen and weighing only 1.76 oz, easy to carry and store; pocket clip design allows it to be securely clipped in your pocket, notebook, etc., and not easy to fall and lost; pen style design ensures that the noise meter fits comfortably in the hand, and the non-slip design on the sides and on the back ensures that the noise meter fits comfortably in the hand, and the non-slip design on the sides and on the back ensures that the deceleration ibel-Mibel-M Easy to hold and resistant to falling
- Wide range, high accuracy: Mastfuyi decibel meter uses a precise electret condenser microphone to capture sound, measures sound level 30 dB to 130 dB. It is factory calibrated, with high accuracy of 1.5 dB, frequency from 31.5Hz to 8KHz. Widely used for monitoring noise level in communities, home theaters, audio systems, automobiles, workshops, schools, offices, factories
- Fast and slow measurement: the SPL has the function of converting fast and slow response speed, more specialized functions for a wider range of applications. In FAST mode, the sensor samples the signal 8 times per second, which is suitable for measuring transient noise or momentary changes in noise; in slow mode, it samples 1 time/s, which is suitable for continuous noise measurements, and displays the average level of fluctuating noise
- Multifunctional: MAX lock function to continuously record the highest readings during sampling time, easy to read and record data; a low battery indicator appears on the screen when the battery is low to remind the user to replace the batteries in time; sound level indicator lights up green when below 60dB and red when above 60dB as a visual warning
- A-rated measurement: this noise meter contains an A-rating to simulate the frequency of low intensity noise for the human ear, it is more accurate and professional for detecting environmental noise
