The freezing point tester is designed and manufactured in accordance with the provisions of the Chinese National Standard GB/T510 \"Method for Determining the Freezing Point of Petroleum Products\". This instrument features a new type of compressor, an advanced digital temperature controller, and a unique cooling bath, which ensures excellent cooling performance, high temperature control accuracy, and stable uniformity of the cooling bath temperature. It is suitable for use by organizations involved in the extraction, production, and use of oil products, as well as various relevant universities and research institutions, for determining the freezing point of petroleum products. I. Main technical features of the freezing point apparatus: 1. The work surface is made of stainless steel; it includes one cold tank and two cold baths, with the two cold baths being at the same temperature. II. By utilizing unique specialized technology, the cold tank does not require coolant, resulting in fast cooling speed and high efficiency. The temperature of the cold tank can reach -30°C, with a temperature control accuracy of ±0.5°C. The instrument has a desktop design, is simple and elegant in appearance, comes with all necessary accessories, and is easy to use; once purchased, it can be used to conduct pour point tests. III. Main technical parameters and specifications of the freezing point detector: Operating power supply: AC 220V±10%; 50Hz. Operating cold tank: Single-tank with two baths, with isothermal conditions for the two baths. Cold tank temperature control: Room temperature to -30°C. Temperature control accuracy: ±0.5℃5. Refrigeration system: New-type refrigeration compressor. Ambient temperature: ≤30°C. Relative humidity: ≤85%. Total power consumption: not more than 700W. This concludes the introduction to freezing point testers. We hope it has been helpful to everyone. If you have any needs regarding freezing point testers, feel free to contact us for consultation.
