Petroleum Pour Point & Cloud Point Tester
GB/T 510 · GB/T 3535 · Cascade Refrigeration · No Alcohol Needed
Pour point is the lowest temperature at which an inclined oil sample starts to move; cloud point is the highest temperature at which cooled oil stops moving — both measure low-temperature fluidity. This determinator follows GB/T 510 and GB/T 3535 and is mainly used for transformer oil, lubricating oil and similar products. Embedded temperature control with LCD display, cascade refrigeration and metal-bath cooling deliver fast, stable cooling without alcohol or other cooling media. The double-aperture design tests pour point, condensation point, cloud point and cold filtration point without mutual interference.
