Web Information

The Phipps & Bird programmable jar testers offer a new level of precision by utilizing six operator programmable memory banks that offer virtually unlimited stirring capabilities:

  • Each bank may be programmed with paddle speeds from 5 to 300 rpm in 1-rpm increments
  • 1 second to 59 minutes and 59 seconds
  • Programmable Audio Signals

The stirrer may be run sequentially through the memory banks, independently in any one of the memories, or continuously at a selected speed. Turning the stirrer off does not erase the programmed information. It permits automatic transitioning from a fast mix/short run to a slow mix/long run, or any combination of speeds and times desired to replicate actual plant conditions and operation.

Constructed on a powder-coated steel uniframe chassis, the PB-900 features an LED floc illuminator built into the base, and stainless steel 1" x 3" paddles, which are adjustable to a maximum depth of nine inches. The unit comes complete with:

  • Standard round glass, 1-liter laboratory testing beakers (6)
  • Includes dust cover and a one-year manufacturer's warranty

All Phipps & Bird JarTesters are 24VDC and come complete with an adapter for 120V/60Hz and 220V, 50/60Hz power sources.
