5 Minute Jar Tester – LabSense

Used to determine optimal coagulant dose on a water treatment plant Pi’s range of Laboratory Charge Analyzers accurately measure colloidal and ionic charge using the streaming current principle (electrokinetic charge), which is comparable to zeta potential. Charge demand is determined with titration to the isoelectric point using the plant coagulant, either manually or by use of an automatic titrator.

In addition, the LabSense can help (in conjunction with jar testing) to determine the optimum alkali addition in soft water applications.

Pi’s LabSense Laboratory Charge Analyzers are intuitive, flexible, and give great repeatable charge demand determinations time after time.

Much quicker to get a result in changeable conditions, the LabSense has earned the nickname “The 5 Minute Jar Tester”.

Options

Titration of the coagulant can be performed manually on the LabSense 1, or with the touch of a button using the auto-titration features that come as standard on LabSense 2 and LabSense 3. The automatic titration feature further simplifies the testing process and helps ensure the most accurate and reproducible results possible.

Some pH adjustment may be required to achieve accurate test results. An option for pH measurement allows the user to also quickly determine the dosage rate of additives like lime or caustic when needed to raise the coagulation pH of low alkalinity waters. pH measurement is included on LabSense 3, and is available as an option for LabSense 1 and LabSense 2.
