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. Review: Professional grade - Pro grade instrument. Can be calibrated with separately purchased calibrator. ## Features - Β±1dB high accuracy meets Class 2 standards - Backlit LCD to view in dimly lit areas - Fast or Slow response time, Data Hold and Min/Max functions - A and C Weighting - 35 to 130dB Range ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075VCNH3J | | Best Sellers Rank | #75,250 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #28 in Sound & Noise Meters | | Brand Name | Extech | | Color | Green | | Customer Reviews | 4.4 4.4 out of 5 stars (355) | | Global Trade Identification Number | 00793950475102 | | Included Components | Complete with microphone wind-screen, wrist strap, and three AAA batteries. | | Item Type Name | Sound Level Meter | | Item Weight | 0.35 Pounds | | Manufacturer | Extech | | Manufacturer Warranty Description | 2 years | | Material Type | Acrylonitrile Butadiene Styrene | | Operation Mode | Automatic | | Style Name | Sound Level Meter | | UPC | 793950475102 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Extech - **Color:** Green - **Item Weight:** 0.35 Pounds - **Material:** Acrylonitrile Butadiene Styrene - **Style:** Sound Level Meter ## Images ![SL510 - Image 1](https://m.media-amazon.com/images/I/6149+h068GL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Accurate, and a great value! *by J***R on June 18, 2017* I have an older DB meter that does straight readings.
