Jar Test Apparatus

Digital Jar Test Apparatus/Jar Tester/ Digital Flocculator with RPM & Timer

Yatherm Scientific manufactures Jar test Apparatus for testing water-soluble polymers. Most importantly used with conventional wastewater treatment processes such as coagulation, flocculation, and sedimentation in the water, wastewater treatment, flock formation test in water treatment plants, and other industrial applications. It is a Laboratory mixing and stirring equipment for the water treatment industry. Yatherm is known for its customization & better quality product with the best price in India.

Jar Test Flocculator used for a uniform stirring of samples in a water testing laboratory. The unit is provided with speed regulator for variable speed, S.S. Stirring shafts with adjustable height, S.S. propeller, and tube light is provided at base for illumination). This efficient machine is manufactured using quality materials and advanced technology. Digital Flocculator can be customized to manual and fully automatic operation with digital display.

The digital Jar test apparatus is a very advanced instrument for Jar Test Calculation in Treatment plants. Jar Test Experiment determines the coagulation and flocculation with the help of the jar Test apparatus. Jar test Experiments depend on the objective of the experiments which is based on sedimentation, the performance of coagulants & PH results. The jar test procedure for water treatment helps in the jar test for an optimum dosage of alum. Jar Test Coagulation can be determined only when you test samples in the jar at a speed of 4 RPM to 16 RPM. High speed will not allow coagulating the treated water when undergoing the Jar test.

Jar Test Apparatus Principle – Digital Flocculator works on the principle of stirring from the top by spindles at low RPM speed. Low-Speed stirring provides information on coagulation & flocculation of untreated water in the jar. Speed regulator can fix the speed and display will show accurate results of RPM. Jar Test calculation is based on the coagulation and which develop in a jar only after mixing of Samples at low-speed RPM.
