Extech 407730 Digital Sound Level Meter

Product Highlights

Accurately Measures Sound Levels

Wherever you need to monitor sound levels, the Extech sound meter will do the job. The meter utilizes a 1/2-inch electric condenser microphone to monitor sound levels from 40 to 130 decibels at an accuracy of +/-2 dB with a 0.1 dB resolution. A windscreen is included to prevent distortion in the readings. User-friendly settings allow you to choose between either A or C weighting. The unit also mounts on a tripod, providing convenient hands-free readings.

The large, 2,000-count LCD display gives readings in large, clear numbers. At the same time, it shows the sound level readings using a fast-responding analog bar graph with a 50-decibel range that updates every 40 milliseconds for viewing varying trends. The unit has AC analog output and records max/min values over time.

Compact, Lightweight Design

The Extech sound meter weighs less than 6 ounces, and is designed to fit comfortably in the palm of your hand. The meter is white with a black-framed screen and black buttons. Useful features include auto power-off, max hold functions, and fast/slow response time.
