Sigma SD900 Refrigerated Sampler, 115V

Easy to Use
The simplified keypad with intuitive icons and scrolling menu on the Hach Sigma SD900 Indoor Refrigerated Sampler assures easy setup. Program set up, even for first time users, is typically less than two minutes. Large keys accommodate gloved hands. Color coded power/stop buttons are easy to identify. The large, 5-line, transflective LED backlit display stays readable in bright or subdued lighting.

Reduced Maintenance
The SD900 sampler also offers reduced maintenance. Extended pump tubing life reduces maintenance costs and pump downtime. The rugged, see-through pump cover stands up to daily use and makes visual inspection and troubleshooting quick and convenient. The desiccant tube— mounted on the side of the controller—and the pump tubing are readily accessible and can be changed in minutes (versus other desiccant chamber designs which require disassembly to reach the desiccant).

Reliable Peristaltic Pump Technology
The strong pump draw and spring loaded rollers ensure that large particulates will not interfere with sample collection. The SD900 sampler uses a positive displacement peristaltic pump. Flow is induced by squeezing a flexible 3/8-inch tube. Spring mounted rollers reduce pump tubing wear and help prevent pump jams. The life time of the pump tubing is 20,000 cycles compared to only 1,000 cycles on other samplers.

Maximize Data with Minimal Effort
Use Hach's SampleView™ software to remotely program the controller, view and download sample history to a computer, save templates, upgrade firmware in the field, and download event logs. Reduce time required for manual record-keeping.

Wide Variety of Applications
The SD900 sampler can be programmed for time-based, flow-based, composite, and multiple bottle sampling setups. Up to three separate sampling programs can be stored simultaneously for optimal sampling flexibility. This sampler is versatile enough for deployment in these sampling locations and applications:

• Monitor influent and effluent waters from municipal and industrial NPDES facilities
• Monitor effluent waters from indirect industrial dischargers for compliance with pre-treatment regulations
• Environmental monitoring including CSO and SSO studies and storm water run-off.
