Liquid Optical Particle Counter Detect process variations quickly with sensitivity down to 0.05 µm BENEFITS Rapid Analysis The Ultra DI® 50 Liquid Particle Counter is designed specifically for de-ionized (DI) water systems and will count and size contaminants as small as 0.5 µm. Larger sample volumes and ultra-low zero counts detect smaller excursions with more relevant statistical data, while shorter sample intervals speed up your analysis time. Respond immediately to contamination with real-time measurement of particles, and move quickly from one sample point to another. A low zero count, large sample volume and high counting efficiency provide you with unsurpassed performance. • Quickly obtain meaningful statistical data with Ultra DI 50’s large sample volume • Save operator time with fast clean-up and the ability to move quickly from one sample point to another • Speed up analysis time by using shorter sample intervals Process Development • Larger sample volumes and ultra-low zero counts detect smaller excursions with more relevant statistical data • Respond immediately to contamination with real-time particle measurement • Facility Net software provides more sophisticated process control with: • email notification • sensor status • tabular and SPC charts • time plots • historical event log records • Set tighter process control limits with low sample-to-sample variation Utilize existing network with Ethernet communication Connect directly to PLC and SCADA systems with 4-20 mA Compatible with ozonated water Stainless steel housing and dual HEPA filtration for use in clean environments A P P L I C AT I O N S • Quantifying particle concentration in ultra pure water (UPW) systems • Filter efficiency measurements • Trending analysis at lower particle concentrations • Detecting bacterial growth in UPW systems • Episodic event tracking and alarming • Continuous sys
