4700 sequential/composite sampler

 

Tough LLDPE molded cabinet is totally rustproof and at home indoors or outdoors Forward thinking is evident from top to bottom in Isco’s groundbreaking 4700 Refrigerated Sampler.  Its rotationally-molded polyethylene construction, user-friendly controls, and workplace-savvy features make it the first choice for stationary sampling in both municipal and industrial wastewater applications. Control and programming are fast, simple, and easily accomplished on-site.  A unique slide-out bottle rack eliminates awkward stooping and bending  to reach sample containers. The controller actively regulates and displays the sample compartment temperature, and logs a 24-hour summary to confirm proper sample cooling.  You can download the temperature record with a basic utility program such as HyperTerminal. Isco tough - and environmentally friendly, too! The 4700 ushers in a new standard for weather and corrosion resistance.  The tough, double-wall LLDPE cabinet shrugs off exposure to weather and harsh environments.  It’s filled from top to bottom with insulation for efficient, economical cooling even in hot, humid environments.  Heat-treated polyester powder coating protects the refrigeration system, ensuring long life and reliability in corrosive treatment plant conditions. Standard Features Composite or sequential sampling Operating range of -20° to 120°F (-29° to 49°C) – without additional heaters Four digital alarm outputs 4-20 mA flow meter input Powerful 1/5 HP compressor delivers energy-efficient, high-performance cooling Application Versatile sampling modes make the 4700 ideal for wastewater compliance monitoring. Uniform time intervals – uniform sample volumes Uniform time intervals – flow-proportioned sample volumes Uniform sample volumes – flow-proportioned time intervals Specifications Isco 4700 Refrigerated Sampler Size (HxWxD): 51 x 28 x 33 in (130 x 72 x 84 cm) Weight: (empty) 159 lb (72 kg) Bottle configurations: 12 different configurations available. 24 bottles, 1-liter PP or 350 ml glass; 4 bottles, 10-liter PE or glass; 2 bottles, 10-liter PE or glass; 1 bottle, 20-liter PE or glass; 1 bottle, 10-liter PE or glass; 24 ProPaks, 1-liter wedge-shaped; 1 ProPak, 10-liter round Refrigerator body: Linear low-density polyethylene (LLDPE) Power requirements: 120 VAC, 60 Hz, or 240 VAC, 50 Hz (specify) Operational temperature: -20° to 120°F (-29° to 49°C) Pump Intake suction tubing: Length - 3 to 99 feet (1 to 30 m); Material - Vinyl or PTFE-lined vinyl; Inside diameter - 3/8 inch (9 mm) Pump tubing life: Typically 1,000,000 pump counts.
