The PortaCount™ Respirator Fit Tester 8040 is a quantitative respirator fit tester that supports respiratory protection programs throughout the entire fit test process; from training and mask selection, through compliance. *Tablet and laptop are not included with the...

The 7525 IAQ Meter measures and data logs multiple parameters such as carbon dioxide (CO2), temperature, and humidity. It calculates dew point, wet bulb temperature, and percent of outside air.

The Personal Impactor is a lightweight personal sampler for collecting airborne particles in the PM2.5 and PM10 size ranges. PM2.5 and PM10 particles are airborne particles less than 2.5 µm and 10 µm. They are frequently used to provide a measure of airborne particle...

Measure PM1, PM2.5, Respirable, PM10, or total PM size fractions. DustTrak Environmental Monitor 8540 is a data-logging, light-scattering laser photometer that gives you real-time aerosol mass readings. It uses a sheath air system that isolates the aerosol in the optics...

TSI thermal mass flow meters provide accurate results with multiple data output options.

All TSI gas mass flow meters integrate flow, absolute pressure, and temperature sensors to deliver readings and compensate flow measurements.

Balancing hydronic systems reduces energy consumption, saves money and enhances system performance.

Respirator Fit Test Adapters enable quantitative fit testing for individuals wearing their own respirators.

TSI Air Velocity Transducers are ideal for both temporary and permanent installations for air velocity measurements
