A:Product Introduction: DSHD-11143 Lubricating Oils Rust Tester is designed according the national standard of People's Republic of China GB/T11143 Test Method for Rust-Preventing Characteristics of Inhibited Mineral Oil in the Presence of Water. DSHD-11143 Lubricating Oils Rust Tester is applies to evaluate rust-preventing characteristics of inhibited mineral oil, especially the rust-preventing characteristics of the turbine oil to iron parts in the presence of water. DSHD-11143 Lubricating Oils Rust Tester is also suitable to evaluate rust-preventing ability of other oils, such as hydraulic oil, circulation oil, as well as liquid, whose gravity is greater than water.
