Protmex PT6708 Sound Level Meter, Digital Decibel Reader Measurement, Range 30-130 dB, Accuracy 1.5dB Noise Meter with Large LCD Screen Display, Fast and Slow Selection (Batteries Include)

Protmex PT6708 Sound Level Meter, Digital Decibel Reader Measurement, Range 30-130 dB, Accuracy 1.5dB Noise Meter with Large LCD Screen Display, Fast and Slow Selection (Batteries Include)

• 【ACCURATE AND SENSITIVE DB METER】 High-quality AD636 chip, low power consumption, professional measurement. It can respond within 0.5s, and quickly display accurate measurement results. Our sound level meter utilizes an electric condenser microphone to monitor sound levels from 30 to 130 decibels at an accuracy of +/-1.5 dB with a 0.1 dB resolution.
• 【FAST AND SLOW MEASUREMENT】 The decibel gauge has the function of converting the fast and slow response rates. The fast response rate uses a time constant of 0.125s/time for general environmental measurement. The slow response rate uses a 1s/time constant, which is used for environmental measurements with relatively large changes in noise levels. Also, have MAX, data hold, and under/over, dB/SONE unit selection functions. Note: Can not keep and generate a report directly from the device.
• 【A/C WEIGHTING NETWORK SELECTION】 A weighting model: Simulate the characteristics of human hearing, which is suitable for the detection of ambient noise; C weighting mode: Actual sound level, which is suitable for the sound pressure analysis of machine motors and machines. This uses to measure the sound level of sound equipment in Work and Life: such as factories, workshops, schools, residential, office areas, traffic roads, audio, and other occasions. Also applies to noise engineering, product quality control, health control, and so on.
• 【ANTI-SLIP AND ENERGY-SAVING SPL METER】 The decibel gauge used a composite material injection molding process with an anti-drop structure design, power saving, high reliability, and high-efficiency circuit, easy to use in multi-environments. The Protmex noise meter with the backlight feature is appropriate for gathering sound data at night. To save power, the backlight auto power-off function is provided.
• 【Protmex 24/7 SUPPORT】 PT6708 sound meter complies with IEC651 Type 2 and SI.4 Type2. CE (LVE, EMC ), RoHS approved. We are engaged to bring quality products to more families and your choice and recognition will always be our greatest support. We will provide 7*24 online friendly support.
