The S130 / S132 is a new generation laser particle counter optimized for applications in compressed air or compressed gases. With quality in mind and with the knowledge of customer needs this instrument is designed for continuous operation 24 hours, 7 days a week. In an alternative version all models are also available for measurements under ambient conditions by means of an internal vacuum pump. These instruments can full fill the requirements stipulated in the compressed air standard ISO 8573-4. Measurement values represent the particle counts per ft³, l or m³ or alternatively in μg/m³. Settings can be done through the integrated display, an external SUTO display or through the service software.
