Feature:
1. HIGH ACCURACY: Noise meter has a high accuracy probe made of pure copper plated material, equipped with windproof noise elimination ball, more stable and accurate measurement.
2. HIDDEN BRACKET: Sound level meter with hidden bracket design, can be opened or closed with the use of the scene, easy to use, portable and space saving.
3. FREQUENCY WEIGHTING: Frequency weighting A is the amount of noise felt by the human ear, and frequency weighting C is the characteristic of mechanical noise.
4. FAST AND SLOW MEASUREMENT: For general environmental measurement use fast response rate, slow response rate for noise level changes relatively large environmental measurement.
5. APPLICABLE: Noise measure device can be used to measure the sound level of sound equipment in work and life, such as factories, workshops, schools, residential, office areas, traffic roads, sound, etc.
