The TSI Quest SD-200 Sound Detector is a compact, lightweight sound level meter designed for measurement of workplace noise levels.

Its intuitive design makes it easy for users to measure sound levels and helps users determine the attenuation of hearing protection that may be required. The integrating feature computes the average sound pressure level, for more accurate assessment of the intermittent sound levels.

Standard features:

• Intuitive interface for easy out-of-the-box operation
• Averaging functionality provides steadier readings in environments where noise levels are highly variable
• Visual LED alerts help users assess the need for hearing protection
• Meets applicable ANSI and IEC Class 2 standards
• Rechargeable battery helps lower total cost of ownership compared to sound level meters that use replaceable batteries

User-Friendly:

• Simple four-button navigation to perform all functions
• Comes ready to take measurements; no configuration necessary

Industry Compliant:

• Meets applicable ANSI and IEC Class 2 standards
• Consistent performance with accurate, actionable readings

Average Sound Pressure Level (LEQ/LAVG):

• Integrating feature computes the average sound pressure level
• Provides stable readings where noise levels typically vary, for easier interpretation

LED alerts:

• Tri color LED’s flash brightly when preset noise levels are reached
• Helps user understand where hearing protection may need to be worn
• Green LED flashes when noise measurements are between 80 and 85 dB
• Yellow LED flashes when noise measurements are between 85 and 105 dB
• Red LED flashes when noise measurements are above 105 dB

Rechargeable:

• Lithium polymer battery provides up to 50 hours of use between charges
• Reduces the cost and hassle of replaceable batteries
