Key features

• •【Compact and Portable】As small as a pen and weighing only 1.76 oz, easy to carry and store; Pocket clip design allows it to be securely clipped in the pocket, on the notebook, etc., and not easily dropped and lost; Pen-style design ensures that the noise meter fits comfortably in the hand, and the non-slip design on the sides and back ensures that the decibel meter is easy to hold and resistant to falling
• •【Wide Ranges, High Accuracy】Mastfuyi decibel meter uses a precise electret condenser microphone to capture sound, measures sound level 30 dB to130 dB. It's calibrated at factory, with highly accurate with ±1.5 dB, frequency from 31.5Hz to 8KHz. Widely applicable for monitoring noise levels in communities, home theaters, audio systems, automobiles, workshops, schools, offices, factories
• •【Fast and Slow Measurement】The SPL has the function of converting the fast and slow response rate, more specialized features for a wider range of uses. In FAST mode, the sensor samples the signal 8 times per second, which is suitable for measuring transient noise or instantaneous changes in noise; in SLOW mode it samples 1 time/s, which is suitable for continuous noise measurements, and indicate the average level of fluctuating noise
• •【Multifunction】MAX lock function to continually record the highest measurements during the sampling time, easy to read and record data; A low battery indicator will appear on the screen when the battery is low to remind the user to replace batteries in time; Sound level indicator illuminates green when below 60 dB and red when above 60 dB as a visual alert
• •【A Weighted Measurement】This noise meter contains A-weighting to simulate the frequency of low-intensity human ear noise, it is more accurate and professional for the detection of environmental noise
• •【48-Month Warranty】We provide 48 months unconditional warranty and lifetime after-sales service
