Shear Stability Tester

Application:

Shear Stability Tester for Polymer Containing Fluids  (European Diesel Injector Method) adopts Germany Bosch dual piston jet pump and atomizing chamber with nozzle & nozzle holder. It is suitable for evaluation of the shear stability of polymer-containing fluids by measuring the percent viscosity loss at 100℃ of polymer-containing fluids. The viscosity loss reflects polymer degradation due to shear at the nozzle.
