Overview
Please note the Avalanche has been discontinued and replaced by the BLZZRD.
Based on the industry leading 6712 controller the Avalanche Auto-Sampler combines on-the-go cooling via a 12-volt deep cycle battery (delivers 48 hours or more of refrigeration) or AC power, with the advanced control, communication and data logging features of the 6712 controller. The power-saving cooling system remains on standby until the first sample is drawn, and then switches on to preserve the samples until they are collected.
Complex programs can be easily entered to suit your needs. Available routines include: sampler pacing by time, non-uniform time, flow or external event; pause and resume for intermittent discharge flow monitoring; and random interval sample collection. Bottle configurations include 5 gallon and 2.5 gallon composite as well as 4 x 1 gallon and 14 x 950 ml sequential.
Standard Features
- 512Kb standard memory gives great flexibility for logging data.
- 'Plug and play' connection provided by SDI-12 interface - Compatible with measuring devices including multi-parameter sondes from leading manufacturers.
- Watertight and dustproot controller enclosure (NEMA 4x, 6 (IP67).
- Simple Setup using standard programming (extended programming for more advanced features).
- Patented pump revolution counter - Tells user when pump should be replaced and ensures accurate sample volumes.
- Sample delivery velocity of 2ft/sec (EPA-recommended), even at head heights of 26ft.
