Stanhope-Seta particle counters provide reliable results for determining the particle concentration in liquid fuels and oils. The size, number and distribution of particles help to determine the cleanliness or suitability of the sample for its intended application. Routinely monitoring particles can save both time and money by reducing equipment downtime. Particle counting is also used to assess fuel cleanliness, where the problems caused by particles are blockage, wear and erosion in fuel systems.
