5800 Refrigerated Sampler

The answer to the rigorous demands of wastewater monitoring 

 

The 5800 Refrigerated Sampler is Isco's answer to the rigorous demands of water monitoring. With user-friendly controls and workplace-savvy features, the 5800 is the only choice for stationary sampling in both municipal and industrial wastewater applications. 

Along with easy control and on-site programmability, it also has a unique slide-out bottle rack that eliminates awkward stooping and bending when retrieving sample containers. 

The controller actively regulates and displays the sample compartment temperature, and logs a 24-hour summary to confirm proper sample cooling. Not only can you download the temperature record with a basic utility program such as Tera Term, you can also view this information on the unit display. 

Isco-tough - and environmentally friendly, too 
The 5800 Sampler follows the Isco standard for weather and corrosion resistance. The tough, double-wall LLDPE cabinet shrugs off exposure to weather and harsh environments. It is filled from top to bottom with insulation for efficient temperature control for keeping samples cool in hot, humid conditions and has heaters to keep the samples from freezing in cold conditions. 

Heat-treated polyester powder coating protects the refrigeration system, ensuring long life and reliability in corrosive treatment plant conditions. 

Advanced delivery system 
The 5800 Sampler uses Isco's proven peristaltic pump to deliver samples at the EPA-recommended line velocity of at least 2 ft/s (0.6 m/s), even at head heights up to 25 feet (7.6 m). 

Sample volume accuracy is assured by the pump revolution counter and Isco's liquid detection system. Pump tubing replacement is simple and fast without requiring tools. A safety interlock disables the pump during tube replacement.

6712FR Fiberglass Refrigerated Sampler

Advanced 6712 sampling in our top-of-the-line FR refrigerator 

 

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.
