Used PARTICLE MEASURING SYSTEMS 7620 SI #9168721 for sale

PARTICLE MEASURING SYSTEMS 7620 SI is an electronic test equipment device designed for efficiently monitoring airborne particle contaminants. It is made up of a wide variety of components, including a digital control module, multiple test chamber options, a size bin-integrated profile calculator, and an optical particle counter. It has a wide range of capabilities suited for numerous particle analysis applications, including ISO 21501-4 in-situ measurements, on-line particle counting, cleanroom contamination control, and particle size distribution analysis. The digital control module of 7620 SI contains a 32-bit processor, dimensional display and text entry, a ventilated cabinet, a set of removable filter elements and optional accessories like a sampling accessory and an outside air calibration adapter. It is capable of executing all internal calculations, controlling the hardware components and displaying the particles measurements. The control module is also equipped with a modem for remote control and data logging. The test chamber options offer a wide array of features, including both exhaust and ambient sampling, as well as high-performance sonic nozzles for precise airflow control and automatic bubble detection for absolute accuracy in particle measurement. They can accommodate up to five size bins, from 0.2 to 10 microns, and have a probing depth of up to 100mm. The size bin-integrated profile calculator enables PARTICLE MEASURING SYSTEMS 7620 SI to automatically report and store the particle size distributions in the ISO 21501-4 and ISO 20115-7 formats. This feature allows the user to investigate contaminant levels and potentially identify potential sources of contamination. The optical particle counter enables users to identify and count the different types of particles present in a sample, including dust, smoke, fibers, and aerosols. The higher the flow rate at which the particles are measured, the more accurate the data produced. This allows users to identify the most relevant airborne particle contaminants and quickly take corrective action. Finally, 7620 SI has a wide variety of accessories, including stainless steel sample tubes, sample pumps, and extra filters, to allow the user to customize their setup to suit their individual requirements. All of these components come together to create a comprehensive testing solution for a variety of particle analysis applications.
