The TUFF line of personal air-sampling pumps features a sealed case that protects pumps from damaging moisture, extreme temperatures, solvents and impacts. With a flow range of 5 mL/min to 4.5 L/min, TUFF pumps are ideal for a wide range of occupational applications, including abatement sampling and industrial hygiene monitoring of dusts, fumes and gases.
