The TSI Quest™ Sound Examiner Sound Level Meters SE-400 are engineered to accurately measure noise levels in highly variable environments, including those that require intrinsic safety. These meters compute average sound pressure level (LEQ/LAVG) over the run time, helping you to more accurately assess occupational and environmental noise levels. All models are ready to use with no set-up required.
Intuitive interface allows for out-of-box use with little to no training
User selectable data logging intervals for download and analysis with TSI Quest Detection Management Software (sold separately)
Averaging functionality allows for easy measurement in variable environments
Printing capability with optional digital printer* provides hard copy documentation in the field
Choose from models with Class/Type 1 or Class/Type 2 microphones, dependent on your application
SE-401 and SE-402-R models include removable preamp
Meets applicable industry standards
Useful tool as part of a Hearing Conservation Program; be confident that data collected is accurate
* Not available on Intrinsically Safe models.
