Particle calculator tools
Convert particle count and area into concentration, and get the ISO 14644-9:2022 SCP surface cleanliness level in seconds.
Whatever you build, the physics is the same. Contamination found late is expensive.
You've measured the particle concentration on your target surface. Now you need the number that everyone, from your process engineer to your customer's quality department, will actually recognize. That is the SCP level from ISO 14644-9:2022.
Our free Fastmicro Particle Calculator Tools give you that answer instantly.
Measuring is the hard part. Grading it doesn't have to be.
Step 1
Particle concentration calculator
Calculate the particle concentration of the target surface from the cumulative particle count and the sampled area.
Then use the result in the SCP grade level calculator below.
Step 2
SCP grade level calculator
Calculate the SCP grade level of the target surface according to ISO 14644-9:2022 from the particle concentration and the considered particle size. Plot your measurements on the chart, and download the chart and the table as a PDF.
