Extech 407730 Digital Sound Level Meter

Whether you’re monitoring workplace machinery, installing audio or alarm systems, or handling product noise certification and reduction, the Extech Digital Sound Level Metre gets the job done. This metre accurately monitors sound levels in a range from 40 to 130 decibels. It displays results in the large LCD display in two different ways, either by number or a fast-responding analogue bar graph. The lightweight metre easily fits in your hand and can be used wherever you need it. Wherever you need to monitor sound levels, the Extech sound metre will do the job. The metre utilises a 1.3cm 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. 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 analogue bar graph with a 50-decibel range that updates every 40 milliseconds for viewing varying trends. The unit has AC analogue output and records max/min values over time. The Extech sound metre weighs less than 180mls, and is designed to fit comfortably in the palm of your hand. The metre is white with a black-framed screen and black buttons. Choose between either A or C weighting, auto or manual ranging. Other useful features include auto power-off, max hold functions, and fast/slow response time. Record sound values over time to track sound changes.
