Dryden Engineering Q-III Surface Particle Detector: Application
Application:
Dryden`s research on surface particle contamination culminated in 1992 in the development of the Surface Particle Detector, which was later enhanced in 1995.
The Model DE3496 SPD, Rev. provides particle concentrations per in.2 or cm2 in five sizes from 0.3 µm to 10 µm. It measures surface contamination in and on process equipment, product containers, minienvironments, tables, benches, walls and any nominally flat surface. It detects particles sizes from 0.3, 0.5 1.0, 5.0 to 10 microns. All five channels of data are gathered at the same time, while one channel is displayed. Selectable sample times are 1, 3 and 6 seconds, with a flow rate of 1 cfm.
Options include an external printer, carrying case with casters, portable cart, an exhaust ULPA filter, custom probes and a 90-degree handle.
