Isco Avalanche® Multi-bottle,
Refrigerated Portable Sampler
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

Optional mobility kit includes pneumatic tires
for ease of transport over rough terrain, and
a convenient battery platform.

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.

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.
