Quest Technologies' Basic Series Sound Level Meters provide you with extremely easy-to-use tools for obtaining the most commonly required noise measurements, such as SPL, Lmin, Lmax, Leq/Lavg, and Peak.
With Quest, you get these features and conformance to independent sound level meter performance and intrinsic safety standards. The Basic Series delivers the kind of red, rugged and reliable performance that has become the hallmark of Quest Technologies.

The new NoisePro Series dosimeters and latest Quest Suite® Professional Applications Software provide “The System Solution” for professionals responsible for occupational hearing conservation.
More than just a recorder of history, “The System Solution” from Quest serves hearing conservationists needs on three unique fronts. An Optional Vibrating Belt Clip promotes the usage of hearing protection and/or self-management of daily noise exposures. The convenient Go/No- Go Screen Icons provide technician and worker-friendly indications of exposure status. Powerful Quest Suite Professional Application Software enables the user to perform Engineering and Administrative Controls Simulation prior to their purchase or implementation. This includes task-based assessments using dosimeter and/or sound level meter studies. But the benefits don't end there.

The marketplace is saturated with sound level meters that provide basic summary noise data such as overall Lmin, Lmax, Leq/Lavg, Peak, Dose, Exposure, TWA and the like. These kinds of summary data can confirm that a noise problem exists but do little to help users trouble-shoot or resolve the problems found. Determining potential and most appropriate methods for correcting excessive noise levels requires a more detailed understanding of the nature of the noise. Unfortunately, obtaining more detailed information historically has meant users must deal with very complex sound measurement instruments and software that are difficult to learn, a challenge to operate confidently and highly prone to operator error. For those that dare venture into the complex world of advanced noise analysis questionable measurement data and unplanned time and expense is often experienced. For the rest of us, keeping things simple may mean choosing to ignore noise problems for fear of the complexities and costs involved.
