MEASURING TOOL

This listing includes: 1 unit of digital sound level meter (30-130 Db).

This high-precision high quality high accuracy SoundLevel Meter (30 to 130 Db) has been designed to meet the measurementrequirement of Safety Engineers, Health, Industrial Safety offices and SoundQuality control in various environment.

Great for noise pollutionmonitoring.

It provides a reliable, accurate andfast way to measure sound level and calculate the decibel of factory,office, traffic, home theater setup, health and safety compliance, vehiclenoise testing and audio system. Also measures both A & C frequenciesto get the right response for the human ear, as well as fast or slowresponses to get an "ambient" reading or a short noise.

Additionally, it’s extremely easy-to-use. Just press one button and resultswill be displayed instantly on the screen, and simply setting the range, theaccurate decibel can be calculated.
