Introduction to the Petroleum Freezing Point Tester
Designed to meet diverse customer requirements, this high-quality instrument complies with the national standard GB/T510 – Method for Determination of Freezing Point of Petroleum Products. It is a low‑temperature apparatus suitable for testing petroleum and petroleum products.
The freezing point tester integrates three main systems: refrigeration, control, and measurement. It features internationally advanced compressor cascade refrigeration technology, offering fast cooling rates and a low achievable temperature. The unit supports automatic timing and includes an alarm function, helping to reduce experimental errors and enhance measurement accuracy.

Quality assurance – The tester provides critical data on low‑temperature behavior, helping ensure the quality and performance of petroleum products. For products used in cold climates, avoiding freezing‑related issues is essential.
Regulatory compliance – Specific standards govern freezing point measurement; adherence is crucial for both safety and environmental protection.
Wide applicability – The instrument can be used on a variety of petroleum‑based products, ranging from crude oil to refined fuels and lubricants.
R&D support – In the development of new petroleum products, understanding the freezing point is vital to confirm that they meet required performance specifications.
Product improvement – Data obtained from the tester can guide the formulation of products with suitable additives or the enhancement of existing products to improve low‑temperature performance.
