Advanced Delivery System
The peristaltic pump delivers samples at the EPA recommended velocity of 2 ft/sec., even at head heights of 26 feet. No other brand of automatic sampler achieves this level of performance!
Step-by-Step Programming
You can 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
Random interval sample collection
Data Loggin
Avalanche is also a powerful data logger. Sampling, flow, rainfall, and water quality data can be stored in its 512 KB memory.
SDI-12 Interfacing
The Avalanche functions as a SDI-12 logger and connects to any sensor that fully implements the protocol standard.
In addition, Isco has defined extended commands to enable “plug and play” communications and ease of programming. These commands are implemented by the sensor manufacturer. Data are identified and logged by their specific type.

Typical areas of application :

Stormwater run off compliance
Enforcement Monitoring
TMDL and watershed monitoring
Any application that requires advanced sampling with reliable on-demand cooling,communications and data logging for water quality, flow and rainfall parameters.
