Lightweight, self-contained and designed to be very portable, this is the smallest version of our automatic sampler. The Pelican case is extremely durable and strong. It uses a 2.5 gallon bottle for Composite only sampling. It is packaged with hose, strainer, battery, charger, bottle (with bottle full shut-off) and a controller with many of the same programs available on larger units. When closed, it is rated NEMA6. Power can be supplied through the internal battery or by external power supply.
