The PAMAS SBSS WG is a particle-counting system for bottle samples. The system is adequate for the measurement of water-based hydraulic fluids (Water-Glycol) used in the offshore industry. The instrument may be programmed to measure a sample without the need for an operator, like pre-filling the internal dead volume, degassing the sample with a vacuum, pressurizing the sample for a number of measurement runs, and relieving pressure at the end. High accuracy and repeatability, fast purging, and back flush possibility are the key benefits of the system. It can be used as stand-alone instrument or controlled by the software PAMAS PMA for the analysis of measuring results in most common quality standards
