In adding TSI Inc's product line to our existing lineup, we add another trusted and recognized brand to our customers who look to Concept Controls for the highest standards of protection and worker safety.

TSI Incorporated also has Quest products that expland their products by adding noise, environmental, and heat stress monitors. These products are a natural fit with the health and safety product line that already includes industry leading PortaCount Fit Testers and DustTrak Monitors. TSI continues to serve the global market by investigating, identifying and solving measurement problems. As an industry leader in the design and production of precision instruments, TSI partners with research institutions and customers around the world to set the standard for measurements relating to aerosol science, air flow, health and safety, indoor air quality, fluid dynamics and biohazard detection.


TSI prioritizes participation in societies and standards committees. TSI's engineers have chaired, sat on committees, or have otherwise been active in pioneering organizations, including:

  • ASHRAE - American Society of Heating, Refrigeration, & Air Conditioning Engineers
  • ANSI - American National Standards Institute
  • AIHA - American Industrial Hygiene Association
  • AAAR - American Association for Aerosol Research
  • SICCA - Shanghai Indoor Contamination Control Industry Association
  • Singapore Accreditation Council

Respiratory Fit Testing Instrumentation

From quantitative fit testing equipment to mask integrity testing equipment, TSI helps you comply with regulated standards to ensure your workers' respiratory safety. Passing a real-time quantitative respirator fit test proves that the face piece is sized and donned correctly, as well as provides for valuable opportunity for training. The PortaCount Respirator Fit Tester can test all types of respirators, including N95 filtering face piece respirators.

HEAT STRESS Monitoring

With TSI’s intuitive QUESTemp Series Heat Stress Monitors we simplify your heat stress management by removing the time-consuming and complex processes. TSI's Heat Stress Monitors are designed to quickly and accurately evaluate potential heat stress environments. These instruments deliver high-performance monitoring using Wet Bulb Globe Temperature (WBGT) sensing technology, the standard for heat stress management, and the calculation of a WBGT Index value.

Dust Monitoring Instrumentation

TSI Aerosol Monitors offer real-time, direct-reading results, which is quickly becoming an industry best practice in occupational hygiene, indoor air quality, and outdoor environmental fugitive emissions monitoring using DustTrak and SidePak instrumentation.

Noise Dosimeter & Sound Level Meters Instrumentation

Our personal noise indicators and sound detectors make it easier to measure sound and noise levels in real-time, and determine the level of hearing protection necessary in a particular environment. The Detection Management Software program works with various TSI Quest data logging instruments, allowing you to record, report, chart and analyze exposures to a host of occupational and environmental hazards.
