![]() The stylish blue enclosure of the REED Instruments R8050 definitely stands out from the crowd. It is one of the most expensive options on the market, but it’s well-engineered design offers unparalleled functionality. This meter has dual-range measurement, which allows them to get higher levels of accuracy out of a simple and affordable sensor. Designed specifically for health and safety professionals, there are many features available that will make your job easier. REEDs safety-first design is most evident in this high end sound level meter. These features are important for use in an industrial setting, making this an idea choice for safety professionals. It can show you the change in sound levels over time, and also track frequency changes. This meter also makes it easy for you to track historical data. But thanks to the auto-off feature, it will always conserve power when not in use. This kind of hardware is pretty power hungry, and requires four AAA batteries to run. This hardware is extremely fast to update the display, with only a 40 millisecond delay between sound measurement and notification time.Īlthough the functionality is quite simple, there are a few bonus features that made this meter stand out. For safety applications, the calibration certificate is available enabling you to meet any legislative requirements needed for your documentation. For venue measurements, this is more than accurate enough to get a safe reading. The meter is calibrated to have a maximum error range of 2 dB. It’s got a resolution of 0.1 decibels, so even tiny changes in sound pressure levels are instantly viewable. This meter uses a half-inch condenser microphone enabling it to accurately measure sound levels across a wide range of frequencies. It’s suitable for use in an industrial environment, and the one-year warranty ensures that you’re protected from any unexpected damage. ![]() REC begins measurement, and MAX HOLD keeps the display indicating the highest SPL measured over the duration of your recording.īetween the thick plastic enclosure and the metal condenser microphone enclosure, this meter is built to a high standard. F/S changes the speed and responsiveness of the meter. This adjusts whether it’s focusing primarily on high frequencies or low frequencies, an important feature for omitting resonance. ![]() Below, you’ve got A/C which allows you to choose frequency weighting. On the top you’ve got a power button, and RNG which allows you to change the measured range. Six buttons along the front allow you to control the most important aspects of the meter’s functionality. The display provides both a bar-graph reading, as well as a numerical value showing the current sound level in decibels. It’s got a large LCD display with high-contrast, easy to read text. At only 6 ounces in weight, it’s not something that you’re going to find frustrating to lug around. It’s easy to hold, and can quickly be slipped into your tool belt until you need it.

The dual range model measures 35 to 130 decibels, split into two different levels for higher accuracy in quieter environments. The singe range model – our primary choice – can measure sound levels between 40 and 130 decibels. The 407730 is available in two different options. Extech 407730Īs a prominent manufacturer in the automation and controls industry, Extech put their advanced technology to work in this affordable, but professional-grade sound level meter. We’ll show you what each of them has to offer, and then we’ll help you decide which one is right for your application. First, we’ll take a look at the three best decibel meters on the market. In this guide, we’ll help you narrow down your search. Static final private double EMA_FILTER = 0.If you’re on the hunt for a decibel meter, you’re likely aware that there are plenty of different options out there.
