Nanoparticle Measurement

Nanoparticles are ubiquitous in the atmosphere. One of their key characteristics is that they possess very little mass, but are many in number. And it is for this reason that the current worldwide, mass–based, ambient air quality regulations for particulate matter are ineffective in dealing with nanoparticle concentrations in cities. Nanoparticles enter the environment from a variety of sources that include natural, incidental and manufactured processes. Road vehicles are the main culprit, contributing up to 90% of the total in polluted environments such as busy roads. Consequently the air in such environments contains tens of thousands of these particles.

NanoMet3 - Portable solid nanoparticle counter for vehicle exhaust emission

Testo Particle's NanoMet3 portable solid particle counter is a general-purpose counter that detects airborne particles down to 10 nm. It provides highly accurate measurements over a wide concentration range. As a result, this portable solid particle counter is quite versatile and well-suited for a broad range of applications.


DiSCmini - Portable sensor for particle number and average diameter measurement

The testo DiSCmini is a portable sensor for the measurement of particle number and average diameter, based on the electrical charging of the aerosols. The small size of the testo DiSCmini handheld makes the instrument particularly suitable for personal carry-on measurement campaigns. The testo 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.


ViPR - For sampling, diluting and conditioning of raw gas for particle characterisation

The testo ViPR is a PMP compliant system for sampling, diluting and conditioning of raw gas for particle characterisation. In combination with a condensation particle counter, it measures the number concentration of solid nanoparticles from vehicle emissions in compliance with UNCE R83 and R49 Regulations.
