Compact JarTesters
For smaller labs where space is a limitation, compact Two- and Four-Paddle JarTesters offer all the same features as bench top Six-Paddle models. These compact units are constructed with the same quality and craftsmanship, built on a powder-coated steel uniframe chassis with stainless steel 1" x 3" paddles spaced six inches apart and adjustable to a maximum depth of nine inches. A fluorescent lamp floc illuminator is built into the jar tester base to provide soft, diffused lighting of samples being tested.
PB-980 Series Two-Paddle JarTester
The PB-980 Series Two-Paddle JarTester's small size makes it an ideal tool for chemical sales representatives to demonstrate the effectiveness of their coagulants. Available in Programmable and Standard versions.
PB-750 and PB-950 Series Four-Paddle JarTesters
The PB-750 and PB-950 Series Four-Paddle JarTesters are perfect for the small lab with limited countertop space. Like the PB-980, they are available in Programmable and Standard versions.
Programmable Features
The Programmable feature elevates jar testing to a higher level of precision by utilizing four operator-programmable memory banks that offer 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 off the stirrer 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 of speeds and times desired to replicate actual plant conditions and operation.
Included Components
Each JarTester comes complete with your choice of B-KER2 square, acrylic, 2-liter testing jars or 1-liter round glass beakers.
