5800 Sequential/Composite Sampler

The only choice for stationary sampling in both municipal and industrial wastewater applications

5800 Sequential Composite SamplerThe 5800 Refrigerated Sampler is Teledyne ISCO's answer to the rigorous demands of water monitoring. With user-friendly controls and task accommodating features, the 5800 is the only choice for stationary sampling in both municipal and industrial wastewater applications. 

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 environ​ments. 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, additionally evaporator and condenser coils are const​ructed of 316 stainless steel. This ensures long life and reliability in corrosive treatment plant conditions. 

​For applications within the United Kingdom requiring certification by The Environment Agency, LaserFlow is designated MCERTS Class 2.​​

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.
