Performance
Speed selector settable at: 10 – 15 – 30 – 45 – 60 – 90 -120 – 150 – 200 – 300 rpm
Independent Positions
FC4S and FC6S, 4- or 6- position Floc Tester, permits changing of the speed during operation, up to 300 rpm.
Settable individual speed for each rod means that every single position is independent for the others.
An illuminated back panel simplifies the observation of the samples, whilst height adjustment option for the stirring blades during operation increases its capabilities.
Why Choose Jar Tester
Choose the Jar Tester for accurate, repeatable, and efficient water and wastewater treatment studies. Its independently controlled stirring positions (4 or 6) allow multiple tests under variable conditions, ensuring flexibility in experimental setups. Each rod’s speed is electronically regulated through a DC gear motor, providing stability and precision across a range of 10 to 300 rpm. The adjustable stainless-steel stirring rods and illuminated back panel make it easy to operate and observe results in real time. Designed with a robust epoxy-painted metal body, the unit ensures long-term durability and reliability in laboratory environments. Whether for coagulant optimization, sedimentation studies, or educational research, this Jar Tester delivers consistent performance and dependable data for process evaluation.
