Chemical Stability of Refrigeration Oil Tester
Product model: JF0698
Product Introduction
Metal materials such as steel and copper are put into special test tubes as catalysts, and a certain amount of refrigerating machine oil and refrigerant are injected in proportion, and then the test tubes are sealed. After heating the sealed test tube at a constant temperature for a predetermined time, the chemical stability of the refrigerator oil and the refrigerant was evaluated based on the appearance and color of the refrigerator oil and the catalyst. This instrument is suitable for refrigeration oil with R-12 or R-134a as refrigerant.
