PMS Ultra DI -Â Model 50 -Liquid Optical Particle Counter
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 0.05 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.
