Avalanche® Multi-bottle, Multi-function Sampler

 

The Avalanche® Sampler is based on the industry-leading 6712 controller. Avalanche provides the advanced control, data logging, and communication features of the 6712, combined with on-the-go cooling from either AC power or a 12-volt deep cycle battery. Bottle configurations include 5 gallon and 2.5 gallon composite as well as 4 x 1 gallon and 14 x 950 ml sequential. 

Like the simpler, composite-only Glacier sampler, Avalanche delivers 48 hours or more of refrigeration from a 12 volt deep cycle battery. Its power-saving cooling system remains on standby until the first sample is drawn, and then switches on to preserve the collected samples until a convenient pickup time. You c​​an easily enter complex programs to suit your unique needs. Available routines include: pause and resume for intermittent discharge flow monitoring; sampler pacing by time, non-uniform time, flow or external event; and random interval sample collection.
