Ultra DI® 20
Liquid Optical Particle Counter

BENEFITS
High sensitivity

•t Advanced laser optics and sensors enable

detection of particles down to 20 nm (9nm Au)

•t Obtain meaningful statistical data to detect
particle excursions quickly

•t Fast sample cleanup shortens the time to move
from one sample point to another

Improved monitoring

•t Larger sample volume and low zero counts

detect smaller excursions with relevant
statistical data
•t Respond immediately to contamination with
real-time particle measurement
•t Facility Net software provides more sophisticated
process control with:
•t sensor status
•t tabular and SPC charts
•t time plots
•t historical event log records
•t email notification

Ultra DI particle counters are designed and optimized for the world’s most
advanced ultrapure water monitoring needs.
By counting and sizing particles as small as 20 nm, the Ultra DI 20 system

•t Compatible with ozonated water
•t Two counting modes

•t High resolution – for pure environments
•t High concentration – for filter challenge tests
and lower purity environments

provides unsurpassed particle detection:
