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.
