Specification for the refrigeration type of Ubbelohde viscosity tester: NAI-WS4A、NAI-WS4B
Product Description
The Ubbelohde viscometer (refrigeration type) is used to measure the kinematic viscosity of liquid petroleum products (referring to Newtonian liquids) under a constant temperature condition. Meets the requirements specified in the industry standard SY/T 5651 "Technical Conditions for Petroleum Product Kinematic Viscosity Testers" of the People's Republic of China, and is applicable to the provisions of the Chinese standard GB/T 265 "Determination of Petroleum Product Kinematic Viscosity and Algorithm for Dynamic Viscometers".
Application Range
Widely applicable in fields such as biotechnology, medicine, food, chemical engineering, metallurgy, chemical analysis, petroleum, etc., it provides users with a high-precision, controlled, and temperature uniform constant field source. It is used in research institutes, universities, factory laboratories, and quality inspection departments
Main characteristics: Principal character
1. Adopting an intelligent temperature controller, the temperature control is fast, the response is fast, and the overshoot is small.
2. Imported acrylic glass is used, with good insulation performance and clear observation of the sample.
3. Adopting a desktop design, the instrument has good overall integrity and is easy to use
4. High precision temperature controller with accurate temperature control; Pin's capillary viscometer special type.
