Feature

●High Precision: The noise meter has high sensitivity and high precision microphone sensor, which can measure noise levels from 30 to 130. Accuracy: ±1.5, Resolution: 0.1
●A Weighting, Fast/Low Speed Measurement: A weighting simulates the frequency of low-strength human ear noise and is suitable for detection of environmental noise. For general environmental measurements, fast response speed is 125 milliseconds. If you have a relatively large noise level fluctuation, the slow response speed is 1 second
●Data Hold, Max/Min. Measure: The sound pressure level meter has the max/minimum measurement to indicate the highest/lowest peak of sound generated during a period. The data retention function locks the current readings on top of the sound measurement according to the individual needs
●DIGITAL LCD DISPLAY: High resolution energy saving screen. Long press the backlight button to turn on the backlight and make it easy to see in dark places
●Wide application: mainly used in various scenes of residential, construction sites, factories, restaurants, entertainment facilities, and other environmental surveillance


Description

The NF-562 is a professional noise tester with portable size and stable function.This device can directly test decibel levels in any environment precisely and quickly. It is mainly used to monitor environmental noise levels in construction sites, entertainment facilities, living communities etc. Features: High Precision: The noise meter has high sensitivity, high precision microphone sensor, measuring 30 to 130 noise levels. Accuracy: 1.5, Resolution: 0.1 A Weighting, Fast/Low Speed Measurement: A weighting simulates the frequency of low-strength human ear noise and is suitable for detection of environmental noise. For general environmental measurements, the fast response speed is 125 milliseconds. If the noise level fluctuations are relatively large, the low response speed is 1 second. Data retention, max/min measurement: The sound pressure level meter has a max/min measurement. highest/lowest peak Data retention function locks the current reading value over sound measurement according to individual needs Digital LCD display: High resolution energy-saving screen backlight button to turn on the backlight for easy viewing in dark places: Mainly used in residential, construction sites, factories, restaurants, entertainment facilities, and other environmental monitoring scenes Specifications: Model: NF-562 Material: ABS Display: FSTN LCD Screen Button: 4 function buttons Sensor: Capacity microphone.
