The CLS-700 T corrosive liquid sampler is a compression sampler combined with a LiQuilaz® particle counter for effective measurement of particles in fluids contained in unpressurized vessels. It is ideally suited for testing chemicals containing dissolved gas, where bubbles could be incorrectly detected as particles. The system eliminates bubbles by pressurizing the sample and keeping the bubbles suspended in solution.
