The CVS4200 programmable vacuum sampler from Campbell Scientific can collect samples based on individual customer needs. It surpasses EPA specifications, can pace sampling based on time and flow, and communicate data back to the operator’s desk in real time. It provides rapid transport velocities of samples, meaning more accurate samples, even of solids. Information is easily controlled and viewable on a backlit screen. It is constructed from composite or discrete models, and interfaces with the company’s data loggers for more measurement and control capabilities. Diagnostics have revolutionized the data returned by samplers, when used in tandem with SCADA and other systems, allowing operators to monitor the entire system from one location. 435/227-9632; www.campbellsci.com.
