The TSI Quest SD-200 is a compact Class/Type 2 sound level meter developed for rapid and practical assessment of workplace noise levels. Measures SPL and Leq/Lavg average sound levels across a 45–130 dB dynamic range; offers A/C frequency weighting and Fast/Slow time response. Green, yellow, and red LED indicators provide visual warnings at preset levels, aiding in the rapid screening of high-noise areas.
User-Friendly Portable Design
The user-friendly interface simplifies operation of the SD-200. The rechargeable lithium-polymer battery helps reduce the total cost of ownership compared to sound level meters using replaceable batteries.
SD-200 Measurement Advantage (Leq/Lavg)
Instead, the SD-200 calculates the average sound level, ensuring consistent measurements in fluctuating sound environments.
Long Battery Life and Convenient Charging
The SD-200 unit offers over 50 hours of operation on a single charge and charges easily via a USB interface. Thanks to this advantage, battery issues are avoided in the field and work areas.
Product Documents
Measurement and Standards Approach
The SD-200 is a practical Class/Type 2 sound level meter for rapid noise screening in work areas, comparing different locations, and identifying areas where a more detailed noise survey is required. With SPL and Leq/Lavg values, preliminary evaluations can be conducted in fluctuating noise environments. For statutory employee exposure or regulatory occupational hygiene assessments, the method to be applied, instrument class, acoustic calibration/verification, measurement duration, and reporting criteria must be verified separately in accordance with the relevant standard and prevailing regulations.

Frequently Asked Questions About TSI Quest SD-200
What accuracy class is the SD-200?
The SD-200 is a Class/Type 2 sound level meter utilising a 1/2-inch omnidirectional microphone and meets applicable ANSI/IEC Class 2 performance requirements.
Can the SD-200 measure Leq or Lavg?
Yes. Its integrating capability calculates the average sound pressure level as Leq/Lavg; this feature provides a more stable evaluation in fluctuating noise environments.
What do the green, yellow, and red LEDs indicate?
According to the factory settings, visual warnings are given by the green LED at 80–85 dB, yellow LED at 85–105 dB, and red LED at levels exceeding 105 dB.
Is the SD-200 a personal noise dosemeter?
No. The SD-200 is a compact area/field sound level meter. In applications requiring personal noise dose measurement on the worker over a shift, personal dosemeters such as Edge or dBadge2 should be considered.
