## Description

From the manufacturer Kit Includes Extech 407730 Digital Sound Level Meter Microphone windscreen 4 AAA batteries User manual Whether you're monitoring workplace machinery, installing audio or alarm systems, or handling product noise certification and reduction, the Extech Digital Sound Level Meter gets the job done. This lightweight meter 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 analog bar graph. Records sound levels from 40 to 130 decibels Precise readings with +/-2 dB accuracy and 0.1 dB resolution Dimensions: 9 x 2.2 x 1.7” (230 x 57 x 44mm) Weight: 5.6oz (160g) Professional Digital Sound Level Meter 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. The unit also mounts on a tripod, providing convenient hands-free readings. Large LCD Screen with Dual Reading Displays 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. User-friendly Settings 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. Monitor Workplace Machinery Reduce workplace noise at the source by screening machines and taking action to avoid noise-induced hearing loss in workers. Install Audio or Alarm Systems By monitoring noise levels during the installation of audio or alarm systems, future users will be protected from excessive noise.

Review: Bien pour utilisation à main levée. Sortie analogique inutilisable. - Grosse déception avec ce Sonomètre. Les fonctionnalités de base sont au rendez-vous. La précision est correcte. Et il y a même quelques bonnes surprises avec une vis de calibration, et une vis de fixation pour montage sur trépied. Si vous voulez utiliser ce sonomètre en utilisation de base "à main levée", très bien. Mais alors, pourquoi cette mauvaise note? Parce que j'avais acheté ce sonomètre spécialement pour relier la sortie analogique à un oscilloscope afin de pouvoir tracer les variations de niveau sonore. Hélas, à la sortie "AC", le sonomètre fournit un signal totalement inutilisable. À titre d'exemple, j'ai joint à ce commentaire un graphique montrant ce que je lis lorsque je balance un signal avec une amplitude de 100dB SPL. Si quelqu'un peut interpréter ça, merci de me le dire. À moins tout simplement que mon exemplaire ne soit défectueux? Bref, je renvoie le produit dés que possible...
Review: Accurate, and a great value! - I have an older DB meter that does straight readings. I was looking for something that I could use for averaging and finding peak volumes so I gave this a try. It's not at all expensive, is easy to use, and seems to work correctly. I have a high end calibrated source for my older meter, and when I tried it on the Extech it read exactly the correct value. So in a static situation the meter is very accurate. While I don't have any way to test it for peak or average readings, I'm guessing that it's probably pretty darn close. I plan on using this for measuring shop machine noise levels, and also for monitoring sound levels for the PA for a jazz band I play in. If you need a DB meter, this one will do a good job at a great price.
