- Handheld nanoparticle counter for measuring the number and average diameter of nanoparticles, with a fast resolution (refresh rate) of 1 second (1 Hz)
- Simultaneous recording of particle number concentration and particle size enables the determination of other characteristic parameters, such as particle surface area (lung deposited surface area, LDSA)
- Save data on a memory card, and transfer it to an external computer via USB
- No operating materials, such as working fluid or radioactive sources, are needed – the testo DiSCmini can be operated over extended periods in any position, and with no need to replenish working fluids
- Vibration resistant, and can be operated in any position
- Battery operation of 8 hours, and/or AC power supply for long term measurements
The testo DiSCmini handheld particle counter measures the number and average diameter of nanoparticles efficiently, based on the electrical charging of aerosols. For example, with the testo DiSCmini, you can reliably monitor human exposure to ambient particles such as diesel soot, welding fumes, or industrial nanoparticles. The small size of the testo DiSCmini makes it ideal for mobile on-site measuring tasks.
Health risks due to nanoparticles
Previous studies describe the negative impacts of ultrafine particles on health, based on vague benchmarks. With the testo DiSCmini, it is now possible to measure the particle number concentration and average diameter of nanoparticles. Both are considered in determining health risk.
Typical applications of the testo DiSCmini include the determination of personal exposure in particle-loaded workplaces (due to diesel soot, welding fumes, and industrial nanoparticles, for example), or in vulnerable populations or groups (such as people with asthma, COPD, or other respiratory conditions).
The small size of the testo DiSCmini makes the instrument particularly suitable for mobile on-site measuring tasks and grid measurements of the ambient air. The high measurement frequency of 1 Hz for all three measurement parameters enables the detection of rapid changes in the aerosol.
