This dual-sample apparatus accurately simulates full-scale chemical coagulation and sedimentation processes within industrial, academic, and municipal sectors, helping water treatment professionals effectively determine optimal chemical dosing treatments such as alum.\u003c\/p\u003e\n\u003cp\u003eBuilt for modern lab operational efficiency, the Model 1922 couples advanced digital micro-processing controllers with a totally flat, touch-sensitive keypad for easy cleanup. Dual standalone program memories let lab technicians run automated variable speed sequences between 10 to 300 RPM. Rapid settling evaluations are streamlined via a smart dual-phase timer that alerts upon completion of fast\/slow mix countdown cycles before instantly pivoting into an automated count-up tracking sequence to index precise settling properties.\u003c\/p\u003e\n\u003cp\u003eConstructed around a chemical-resistant powder-coated mild steel body, this jar tester features heavy-gauge stainless steel stirring paddles and spindles.
