Description

General description

This pump attachment is designed for low flow industrial hygiene sampling, such as gas or vapor monitoring, using sorbent tubes. Two needle valves provide independent flow control for simultaneous collection on two tubes but, by closing the flow to one valve, a single tube can be used. The sampler is compatible with any personal sampling pump capable of a 1.5 Lpm flow rate at a load of 25 inches of water. Total flow cannot exceed 500 mL/min. Each sampler comes with two tube protectors, one for small tubes (<2 in. long) and one for large tubes (<41/2 in. long), and tubing required to connect the sampler to the sampling pump.

Features and Benefits

Features:

• Valved mechanism allows flow control down to .001 L/min

• Includes tube covers to fit both large and small tube sizes
