Elevate jar testing to a higher level of precision

These jar testers improve precision with four operator-programmable memory banks that provide virtually unlimited stirring capabilities. Each memory bank may be programmed with paddle speeds from 5 to 300 rpm in 1-rpm increments and run times from 1 second to 59 minutes, 59 seconds in 1-second increments. Turning the stirrer off does not erase the programmed information. The stirrer may be run independently in any one of the memories, continuously at a selected speed or sequentially through the memory banks. Running it in sequential mode permits automatic transitioning from a fast mix/short run to a slow mix/long run, or any combination or speeds and times desired to replicate actual plant conditions and operation.
