Congo Red Thermal Stability Tester

Product Description

Product Description
Product DescriptionTST-300 Congo Red Thermal Stability Tester is used to determine the thermal stability of PVC compounds for insulating and sheathing materials of electric cables. Test principle: Place about (50±5)mg sample into a specified glass tube. The glass tube is placed into oil bath at the temperature of (200±0.5)℃. A Congo red paper or common PH paper is inserted into the glass tube; its other end is folded and hung on the top wall of glass tube. Record the time during the Congo red paper becomes from red to blue (the common PH paper becomes from PH5 to PH3). The time of color change is expression of the thermal stability.Standard GB/T 8815GB/T 2951.7IEC 811Specification ModelTST-3000Temperature range RT~250℃Temperature resolution0.1℃Timer range0~99.99sChamber capacity3000mlGlass tube sizeLength: 1100mmExternal diameter: 5mmInner diameter: 4mmTest paperCongo red paper or PH paper Heating oil required2# lubricating oil or insulating oilHeater power1.25kWPower supplyAC220V 50HzDimensions 420mm×200mm×250mm (L×W×H)
