3710 Composite-only Portable Sampler

Single-bottle sampling up to 4 gallons


3710 Composite-only Portable SamplerThe 3710 Sampler combines simple operation and high volume capacity for single-bottle sampling. It collects composite samples - based on time or flow intervals - in a 2.5 gallon glass or polyethylene bottle, or a 4 gallon polyethylene bottle. Up to 24 sampling stop and resume times can be preset for unattended, automatic sampling. 

Setup and programming is​ a snap. Simply choose the options you need from the selections displayed on the two-line, backlit LCD. 

With a thermal resistance of R-11, you can be assured of maximum effectiveness for cooling samples. A thick, one-inch foam insulated base keeps the unit more rigid, and less affected by ambient temperatures.
