The 6712FR is a sequential or composite refrigerated sampler designed to withstand the harshest indoor or outdoor environments. It features our unequalled "FR" model corrosion-proof refrigerator cabinet molded from polyester resin fiberglass and supported by a stainless steel frame.
A UV-resistant gel coat provides a smooth, non-porous finish for added protection and easy cleaning. Thick, foamed-in-place insulation helps keep samples preserved at the EPA-recommended 39°F (4°C). An automatically controlled, built-in heater ensures that samples won't freeze.
The heart of the 6712FR is Isco's advanced 6712 Controller. It allows you to select different programming modes to assure the most suitable routine for your application. Programming is fast and simple, with on-line help just a key stroke 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 notification, triggered on any combination of up to 16 inputs.
- New SDI-12 interface provides “plug and play” connection with multi-parameter sondes.
- Memory gives you great flexibility for logging environmental data.
- Automatic built-in heater ensures that samples won't freeze, even when ambient temperatures drop to -29°C.
- Durable powder-coated epoxy, phenolic paint, or polyester tubing, protects refrigeration components.
- Sample delivery at the EPA-recommended velocity of 2 ft/sec., even at head heights of 26 feet.
- Pump revolution counter and patented liquid detection sensor ensure accurate sample volumes - and tells you when tubing should be replaced.
