Scope of application This test method covers the evaluation of the ability of inhibited mineral oils, particularly steam-turbine oils, to aid in preventing the rusting of ferrous parts should water become mixed with the oil. This test method is also used for testing other oils, such as hydraulic oils and circulating oils. Provision is made in the procedure for testing heavier-than-water fluids. Function characteristics 1, Reasonable structure. 2, The constant temperature bath, cover with 4 samples. Cup hole, and simultaneously to do four sample test 3,Four stirring rod rotation is designed and made as per The timing belt, smooth and reliable. 4,Stirring rod can move up or down (by Chuck dancer), easy to operate. 5, with temperature control, timing, when The alarm function; 6,stainless steel bath body; Technical parameters 1,Power supply: 220V ± 10%, 50Hz; 2,Measuring range: 0 ~ 100 °C; 3,Temperature accuracy: ± 1 ° C; 4,Temperature sensor: Industrial platinum resistance indexing number Pt100; 5,Temperature display: digital display; 6, The control range: 1 minute to 24 hours arbitrarily set; 7, The time display mode: Digital display; 8,Temperature of The heating power: 600W; 9, The auxiliary heating power: 1000W; 10, stirring motor speed: 1400r/min”
