The ISO 14644-1 limits are expressed in particles/m3 of air. The table below, reproduced from ISO 14644-1, shows how airborne particulate cleanliness is described as the number of particles, of size greater than a specific value, in a fixed volume of air expressed as a concentration. ISO 14644-1, Cleanrooms and associated controlled environments-Part 1: Classification of air cleanliness, is a standard for designating the classification of airborne particulate cleanliness within a cleanroom or clean zone.
Troubleshooting filtered process environments on an as needed basis.Annual or Bi-Annual certification of clean rooms or controlled environments to ISO 14644-1.There are three primary applications categories for air particle counters which include handheld models. What are Handheld Particle Counters used for? Examples - Food and beverage, dairy packaging, hospital pharmacies. Precision, contamination sensitive industrial segments such as Optics, Aerospace, MEMS, Print-heads etc.Yield sensitive electronics manufacturing environments such as semiconductors, flat panel display and hard disk storage industries.Industries that use handheld particle counters can be classified into three distinct categories, each with distinct needs. From medical devices to microelectronics, from aerospace to optics, contamination control professionals routinely make use of handheld particle counters for periodic contamination monitoring and troubleshooting within high cleanliness manufacturing and process environments. Contamination sensitive manufacturing environments can be found in increasingly diverse industries and in many cases a handheld particle counter has proven to be a useful tool. MET ONE pioneered the concept of packaging an optical particle counter into a handheld instrument almost 20 years ago and since that time the technologies now available in our increasingly connected, mobile world have enabled enormous opportunity where saving time and money is of real customer value.
