XH-ST-320 Shear Stability Tester

The XH-ST-320 Shear Stability Tester is a new high-tech product developed by German technology, replacing imported instruments, all major components are purchased directly from Germany. Shear Stability Tester is suitable for shear stability determination of polymer-containing oils. The main unit consists of Bosch double piston jet pump and spray chamber with nozzle and nozzle holder. The polymer-containing oil passes through the nozzle of the diesel nozzle shear stability tester at a certain shear rate to promote the depolymerization of the polymer molecules with poor shear stability, and reduce the kinematic viscosity of the sample to report the sample. The percent drop in kinematic viscosity at the initial 100 °C is used to measure the shear stability of the polymer-containing oil.
