Testo DiSCmini Handheld Nanoparticle Counter


Evaluate health risks by using the Testo DiSCmini to worker exposure to ultrafine ambient particles (UFPs) such as diesel soot, welding fumes, or industrial nanoparticles, or determine risks for people with asthma, COPD, or other respiratory conditions.

The Testo DiSCmini handheld particle counter efficiently measures the number and average diameter of nanoparticles, based on the electrical charging of aerosols. The unit's small size makes it ideal for mobile on-site measuring tasks. The 1Hz measurement frequency for all three measurement parameters lets you easily detect rapid changes in the aerosol.

  • Measures particle size: 10 to 300 nm (Modal value), 10 to 700 nm (absolute)
  • Particle concentration: 1,000 to 1,000,000 Particle/cm³ (typical).  Evaluated particle concentration depends on particle size distribution and mean measurement time.
  • Accuracy: ±30 % typical for size and number; ±100 Particle/cm³ absolute in number
  • Simultaneously measure and display particle number concentration, average particle diameter, and lung deposited surface area (LDSA) with a refresh rate of 1 second
  • No need for any working fluid or materials to operate
  • Vibration resistant, and can be operated in any position
  • Battery operation of 8 hours, and/or AC power supply for long term measurements
  • Save data on a memory card, and transfer it to an external computer via USB
