Mastfuyi Decibel Meter, Digital Sound Level Meter Portable SPL Meter 30dB To 130dB

Product details

• 【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.
• 【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.
• 【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.
• 【Calibration】Step 1: Press SLOW/FAST button and power switch button at the same time, press and hold SLOW/FAST button and don't release it, after power on, press the power switch button briefly, the screen shows MAX to indicate that it enters the calibration mode. Step 2: Set the standard signal source device to 94dB, then align the meter to the standard signal source device, wait for the meter reading to stabilize at 94dB, press the SLOW/FAST button to save, and then press the Power On/Off button to restart the device, the calibration is completed.
