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 count capability allow you to detect smaller excursions with more relevant statistical data, with shorter sample intervals for quick data analysis so you can respond immediately to contamination with real-time measurement of particles. Save time with fast clean-up and the ability to move quickly from one sample point to another. The low zero count, large sample volume, and high counting efficiency of the Ultra DI^® 50 Liquid Particle Counter provide unsurpassed performance and flexibility.
