The TSI Quest SE-400 Series Sound Examiner Sound Level Meters 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.
Standard features:
- 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
- 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
Choice of Microphones:
- User can specify microphone type (Class/Type I or Class/Type II) based on application.
- Select Type II for general duty; Type I accuracy for legal metrology.
Removable preamp:
- Preamp can be easily removed to enable interference-free low-level monitoring, especially for remote use.
Aerodynamic shape:
- Minimises disturbance to sound fields being measured, assuring accurate readings.
Onboard data logging:
- Allows user to capture maximum, minimum and peak values for thorough analysis.
- Can be used with TSI Quest Detection Management Software DMS to manage compliance with hearing conservation programs.
Conformance to standards:
- Meets IEC 61672-1 (2002) and ANSI S1.43-1997 (R2007) standards and is CE certified.
- Intrinsic Safety approvals on SE-401-IS and SE-402-IS.
