Ultra DI® 50 Liquid Particle Counter

The Ultra DI^® 50 Liquid Particle Counter is tailor-made for de-ionized (DI) water systems and is capable of detecting and sizing contaminants as small as 0.05 µm.

It offers benefits such as analysis oflarger sample volumes and extremely low zero counts, which enhance sensitivity and provide more meaningful statistical information. Additionally, it accelerates theanalysis process by reducing sample intervals.

Users can promptly address contamination issues with real-time particle measurement and swiftly transition between different sample points. Its combination of a low zero count, large sample volume, and high counting efficiency ensures exceptional performance.

Benefits

Rapid Analysis

Achieve significant statistical data rapidly by leveraging the substantial sample volume of the Ultra DI 50.

Expedite analysis by adopting shorter sample intervals.

Optimize operator efficiency with swift clean-up procedures and the ability to swiftly transition between sample points.

Process Development

Increased sample volumes and minimal zero counts enhance the detection of smaller excursions, yielding more pertinent statistical data.

Swiftly address contamination through real-time particle measurement.

Facility Net software offers highly advanced process control with:

Sensor status

Email notification

Time plots

Historical event log records

Tabular and SPC charts

Set tighter process control limits along with low sample-to-sample variation.

Easy to Use

Employ users’ current network through Ethernet communication.

Designed for compatibility with ozonated water.

Features a stainless-steel housing and dual HEPA filtration, making it suitable for use in clean environments.

Establish a direct connection to PLC and SCADA systems using the 4-20 mA interface.

Applications
