The world’s smallest nanoparticle counter

Date: 13/7/2017

Testo, Inc., the world’s leading manufacturer of test and measurement instruments, announces the DiSCmini, the smallest handheld instrument for the measurement of nanoparticles. DiSCmini measures: particle number, average particle diameter and lung-deposited surface area (LDSA) with time resolution and logging at 1 second.

The testo DiSCmini operates without working fluids or radioactive sources and works in any orientation. Measurements can be carried out quickly and easily. DiSCmini is particularly efficient for personal exposure monitoring in particle-loaded work space with toxic air contaminants such as diesel soot, welding fumes or industrial nanomaterials. It can be used to access exposure down to a size of 10 nanometres. Raw data files can be imported directly into Excel or analysed with a cross-platform software tool.
