  The oil water content tester is used to determine the amount of trace moisture in liquids with different properties. It has the advantages of high measurement accuracy, fast speed, stable and reliable measurement data, and is widely used in petroleum, chemical, electric power, environmental protection, medicine and other departments. It can quickly measure chemical, petroleum, pharmaceutical, pesticide and other products such as alcohols, oils, lipids, ethers, esters, acids, alkanes, benzenes, amines, organic solvents, pesticides, phenols, pharmaceutical raw materials, etc.  Features  1. Using a 64-bit embedded microprocessor as the main control core, embedded in the mini operating system  2. Constant current detection, high precision, fast measurement speed, with background compensation function, stable and reliable  3. Double circuit balanced titration, test results with less error and higher sensitivity  4. The electrolytic cell adopts the latest waterproof seal design, which has

 Distillation range measurement method refers to the temperature at which a liquid is calibrated to the standard pressure [101.3kPa(760mmHg)], from the 5th drop from the beginning of the distillation, to the temperature at which the test product has only 3 to 4ml or a certain proportion of the volume is distilled A method of scope. Some liquid medicines have a certain distillation range, and the determination of the distillation range can distinguish or check the purity of the medicine. A set of domestic 19 standard grinding mouth distillation equipment is used. A is a distillation flask; B is a condenser, the distillation range is below 130°C and water-cooled, and the distillation range is above 130°C with an air condenser; C is a 25ml graduated cylinder with a graduation of 0.5ml; D is a split immersion type with a graduation of 0.2°C The thermometer has been calibrated in advance. The upper end of the mercury bulb of the thermometer is aligned with the lower wall of the outlet branc

  KR12H Timken ring block oil friction and wear testing machine , also known as Timken testing machine, measures the load-bearing capacity of various plungers (lubricating oil, grease and solid lubricating film): under the specified test conditions, compare the compressor before the oil film ruptures The maximum test force that can withstand is the OK value, which conforms to the national standard SHT0203-1992 grease extreme pressure performance measurement method (Timken test machine method), the friction and wear performance of friction is detected by the method of line contact sliding rubbing, and ASTM D2509 standard. The working principle is: the active part is a standard rotating ring, and the passive part is a fixed rectangular block of standard size. By measuring the width of the strip-shaped wear marks on the rectangular block of the passive test piece under different lengths, the friction force between the friction pair materials, the friction coefficient, the rated pressure b
