Ultra DI 20 Plus Spec

Introduction PMS Ultra DI 20 Plus Liquid Optical Particle Counter

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 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).

Particle Measuring Systems (PMS) is the world leader in sensitivity.

Features Ultra DI 20 Plus
