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 liquid particle counter is one of Particle Measuring Systems’ “Industry Leading Sensitivity” products. This means that there are no products on the market that are more sensitive than these and only PMS offers a line of products covering this many elements of production monitoring. PMS currently leads the market in monitoring performance, sensitivity and reliability in the Ultrapure Water, Chemical and Airborne Molecular Contamination Monitoring fields. PMS’ superior knowledge, technology and service provides High Tech and Chemical manufacturing companies with the most advanced tools to make accurate data-driven decisions, improving both performance and yield.
