Laboratory particle counter for liquids with a viscosity of up to 1600 cSt with an external pressure supply and precise flow rate control

The PAMAS SBSS is a particle counting system for batch sampling. The PAMAS SBSS is the standard instrument used as a reference in many testing labs. The instrument may be programmed to measure a sample without the need of an operator, like pre-filling the internal dead volume, degassing the sample with vacuum, pressurising 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.
