Product information

Floc Testers (also known as Jar Testers) are designed for a range of applications - such as testing the efficiency of flocculation or precipitation agents.

  • For Laboratory Use
    The in-line design makes it easy for users to visually compare multiple samples. The structure is epoxy painted and tested to give to an excellent resistance to the attack of chemical agents and corrosion. The non-skid base keeps the beakers stable during operation.  
  • Dual Digital Displays
    Two displays are located on front panel. One displays the RPM, the other displays the time remaining for the test to complete.  
  • Universal Power Supply
    The low energy (6W) power supply allows the instrument to be connected to all frequencies and voltages in the world (100 - 240 V / 50 - 60 Hz). The devices are supplied with adapters for USA, EU and UK outlets.
  • Stirring Speed Control
    From the front panel it’s possible to select the same stirring speed from 10 to 300 rpm for each position, the real speed is shown on the relative display. In addition, the stirring rods can be adjustable in height without the use of tools.
  • Timer Function
    The timer can be set for a specific number of minutes (up to 999), number of hours (up to 99) or set to continuous operation mode. When the timer expires, the instrument will automatically turn off, allowing for unattended operation of the device.
  • Illuminated Backdrop
    The panel behind the jars is illuminated - making it easy to visually compare samples.
