This high-precision high quality high accuracy Sound Level Meter (30 to 130 Decibels) has been designed to meet the measurement requirement of Safety Engineers, Health, Industrial Safety offices and Sound Quality control in various environment. Great for noise pollution monitoring. It provides a reliable, accurate and fast way to measure sound level and calculate the decibel of factory, office, traffic, home theater setup, health and safety compliance, vehicle noise testing and audio system. Also measures both A & C frequencies to get the right response for the human ear, as well as fast or slow responses to get an "ambient" reading or a short noise. Additionally, it's extremely easy-to-use. Just press one button and results will be displayed instantly on the screen, and simply setting the range, the accurate decibel can be calculated.
