TSI SE-400 Sound Examiner Sound Level Meters

Descriptions of TSI SE-400

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.

Features and Benefits
▪ Red models have Intrinsic Safety approvals
▪ 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
▪ 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
