Chemical Stability of Refrigeration Oil Tester lubricant refrigerator oil chemical resistance apparatus Automatic timing alarm

Chemical Stability of Refrigeration Oil Tester

 Product model: JF0698

Product Introduction

Put steel, copper and other metal materials as catalysts into a special test tube, inject a certain amount of refrigerating machine oil and refrigerant in proportion, and then seal the test tube. After the sealed test tube is heated at a certain temperature for a predetermined period of time, the chemical stability of the refrigerating machine oil and the refrigerant is evaluated based on the appearance and color of the refrigerating machine oil and catalyst. This instrument is suitable for refrigerating machine oil with R-12 or R-134a as the refrigerant
