Sensitivity range: 20 – 100 nm
Designed specifically for ultrapure water systems, the Ultra DI® 20 Plus liquid particle counter from Particle Measuring Systems (PMS®) quickly obtains statistically meaningful data and will count and size contaminants as small as 20 nm. Consistency helps you get more out of your data, even if the instrument moves, so you have more control over your process. The Ultra DI 20 Plus Liquid Particle Counter has a low zero count, large sample volume and high counting efficiency that provides benchmark particle detection. Improved sensitivity allows you to detect process variations more quickly with 20 nm polystyrene latex (PSL) and 9 nm gold (Au).
The UDI-20 is one of Particle Measuring Systems’ “Industry Leading
