Your handheld particle counter is risk mitigation in the palm of your hand!

TSI AeroTrak® Handheld Particle Counters are the gold standard for clean manufacturing or clean room particle counting, risk mitigation, and yield improvement. They're the handheld particle counters to which all others aspire.  

Your TSI particle counter makes your job easier in 3 ways:

  1. Mitigate your risk more effectively and increase process uptime, so you can achieve your goals.

  2. Make it easier to track down particle contamination sources & stabilize your air particle count, so you can reduce process downtime.

  3. Speed up your indoor air quality investigations and make them more accurate, so you can increase process uptime.
