6712C Compact Portable Sampler

Advanced sampling capabilities in a smaller package

The 6712C compact model gives you the world’s most versatile sampler controller in a smaller-diameter package that fits in 18″ and offset manholes. Large, comfortable handles make transporting safe and convenient – even when wearing gloves. The NEMA 4X, 6 (IP67) enclosure is submersible, watertight, and dust-tight. Plug-in 700 Series Modules and the SDI-12 interface make it easy to add flow and parameter monitoring to your 6712-based system.

ISCO’s advanced 6712 Controller allows you to select different programming modes to assure the most suitable routine for your application. Programming is fast and simple, with online help just a keystroke away.

In Standard Programming Mode, the controller walks you through the sampling sequence step-by-step, allowing you to choose all parameters specific to your application. Extended Programming Mode lets you enter more complex programs including “smart sampling” event notifications, triggered on any combination of up to 16 inputs.
