NOTE: The 4700 has now been replaced by the 5800.

The ISCO 4700 MCERTS wastewater sampler is the ideal choice for stationary sampling in municipal and industrial wastewater applications. Programming and controlling the wastewater sampler is fast and easy. The sampler features a slide out bottle rack which eliminates the need for awkward bending to reach sample containers. The sample compartment temperature is displayed and regulated by the controller and logs a 24 hour summary to confirm proper sample cooling. The temperature logs can be downloaded using a basic utility program such as HyperTerminal.

The 4700 MCERTS Samplers have a tough, double wall LLDPE cabinet which creates a new standard of weather and corrosion resistance. The unit is well insulated to ensure efficient, economical cooling. The refrigeration system is protected by a heat treated polyester powder coating, ensuring long life and reliability in corrosive treatment plant conditions.
