Avalanche Sampler datasheet - Teledyne Isco - #1

Text version of the page

Multi-function sampling and data logging with dual-power cooling Avalanche® is based on Isco’s industry-leading 6712 controller. You get all the advanced control, data logging, and communication features of the 6712, with cooling from either AC or battery power. Bottle options include 5- and 2.5 gallon composites as well as 4 x 1-gallon and 14 x 950 ml sequentials. A 12V deep-cycle battery delivers 48 hours - or more- of refrigeration. The power-saving cooling system remains on standby until the first sample is drawn, and only then switches on to preserve the collected samples for pickup. 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. Standard Features Standard and extended programming keeps setup simple when you don't need advanced features. NEMA 4x, 6 (IP67) controller enclosure. SDI-12 interface provides “plug and play” connection with multi-parameter waterquality sondes and other compatible devices. 512kB memory gives you great flexibility for logging environmental data. Sample delivery at the EPA-recommended velocity of 2 ft/sec. at head heights up to 26 feet. Patented pump revolution counter ensures accurate sample volumes - and tells you when tubing should be replaced. Applications Stormwater runoff compliance TMDL and watershed monitoring Enforcement monitoring Advanced sampling combined with data logging and communications for flow, rainfall, and water quality parameters. Isco Avalanche® Multi-bottle, Refrigerated Portable Sampler Optional mobility kit includes pneumatic tires for ease of transport over rough terrain, and a convenient battery platform. Isco temperature control technology accurately preserves samples at 3°C – even under difficult conditions shown above (40°C ambient, 20°C sample temperature).
