Sound Level Meter

Ever want to prove to your students how loud they are in class? You can, with this professional level sound meter.

Of course, this decibel meter is also excellent for teaching principles of sound and illustrating safe and unsafe noise levels.

The lightweight, portable meter features two scales that cover 40 to 80 dB and 80 to 120 dB ranges with the flip of a dial.

Signal oscillator calibration, a capacitance microphone, and an A weighted frequency response help make this meter accurate to ±1 dB; and battery operation lets you take it right to where the sound is. The meter comes with a carrying case, 9 V battery, and an instruction manual.
