Cascade Impactors

Cascade Impactors

TSI’s suite of cascade impactors can collect particles with aerodynamic diameters (cutpoints) from 10 nm to 10 µm, in 3 to 13 different size fractions, and at flow rates of 2, 10, 30 or 100 L/min. The number of stages determines the size resolution of the collected samples, and consequently determines the level of detail of the data generated from the quantitative analysis of these collected samples. MOUDI II impactors have rotating stages. When the stage is rotated relative to the nozzle plate, the impacted particles are deposited in a more uniform manner across the impaction surface. This increases the amount of particle mass that can be collected, reduces the probability of particle bounce and re-entrainment, and optimizes quantitative analysis of the collected samples.

Noise Dosimeters & Sound Level Meters

Noise Dosimeters & Sound Level Meters

TSI's Quest™ Edge Personal Noise Dosimeters are shoulder mounted, providing ergonomic, convenient measurement. Handheld Quest sound level meters measure average sound pressure level over time. All units are compact, with large displays and intuitive interfaces to provide crucial information at a glance and in real-time.

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.
