The BUCK Libra Plus LP-5 air sampling pump is a good choice for a variety of applications in which personal exposure needs to be assessed; it is designed to draw an air sample through analytical media (i.e., cassettes, detector tubes, impingers) at a flow rate between 800 cubic centimeters per minute (cc/min) to 6 Liters per minute (L/min). The single diaphragm pump is encased in high-impact, anti-static Lexan material and proves to be a very quiet pump. The LCD display consists of 2 lines and shows the user flow rate, accumulated volume and elapsed time of the sample. It is also user-friendly, as you choose RUN for sampling and MENU to reset pumps from the main display. This pump is equipped with a patent-pending electronic circuit board that extends the life of the powerful Nickel Metal Hydride (NiMH) triple battery pack (4.8V, 6.45Ah) to ~30 hours (continuous use at 5 L/min). The keypad locking system is password protected for tamper-proof operation and tools are not needed to use and modify the pump.
