Digital Sound Level Meter Gauge with Resolution 0.1 dB Accuracy Plus or Minus 1 dB Leq 35 to 130 dB
Product Description:
The Sound Level Meter is divided into two types: ( AS-156A Accuracy : ±2dB), (AS-156B Accuracy : ±1dB ). Can memorize 30 groups of measurement results and measuring conditions. Permits choice “A” / “C” / “F” weighting and “Fast” / “Slow” response times. Offers 4 measurement parameters: Lp ( soundlevel). Leq (Equivalent Continuous A Sound Level). Lmax (Maximum Sound Level) and LN (Percent of all readings over alarm value set).
Product Feature:
1.DC output :1 0 m V / d B.
2.Auto range selection and digital display with no guessing errors.
3.Can memorize 30 groups of measurement results and measuring conditions.
4. Permits choice “A”, “C” , “F” weighting and “Fast” / “Slow” response times.
5.Offers 4 measurement parameters: Lp (sound level); Leq (Equivalent Continuous A Sound Level ); Lmax ( Maximum Sound
Level) and LN (Percent of all readings over alarm value set ).
6.Use USB data output with connection PC.
7.Provide Bluetooth data outputchoice.
