Personal Air Sampler Line Covers Wide Range of Uses

Casella USA has introduced the Tuff line of personal air sampling pumps featuring a sealed case that protects internal electronics from damaging moisture, extreme temperatures, solvents and impact. Offering a wide flow range from 5 ml/min to 4.5 l/min, the three pumps that comprise the Casella Tuff line are suited to a wide range of occupational health applications, from simple abatement sampling to more specialized monitoring of dusts, fumes and vapors. All pumps incorporate a doubleacting diaphragm mechanism with precise digital control, designed to offer the user real-time flow control and stability across a wide range of sampling media. Navigation is guided by an intuitive user interface displaying real-time flow, sampled volume and run duration, as well as a battery “fuel gauge” and an alarm for flow or battery fault conditions. The pumps feature 4.8 V NiMH rechargeable battery cells with operational run times of five hours, making them the perfect choice when there is no electrical power available. Rounding out the system are accessories, including sampling heats, bubblers, filter media, and sorbent tubes, along with rotameters and calibrators to calibrate Tuff pumps to ensure compliance to sampling methodologies.
