Electrode Paste Softening Point Tester, Digital Ring & Ball Apparatus for Carbon Material Testing

Accurate Testing by Ring-and-Ball Principle

The apparatus fully complies with the Ring-and-Ball testing method. It measures the temperature at which the steel ball starts to sink under a specified heating rate to determine the softening point of electrode paste. Featuring high precision and good repeatability, it meets the quality control requirements of the carbon industry.

Digital Intelligent Temperature Control, Easy Operation

Equipped with a microcomputer-based digital control system, it supports presetting the heating rate and real-time display of temperature and time. The annular heating system ensures uniform heat distribution, guaranteeing comparability of test results for different batches of samples. Operators can complete the test without professional skills.

Wide Material Compatibility, High Versatility

It is not only suitable for electrode paste, but also for testing the softening point of graphite electrodes, modified bitumen, coal tar, resins and other materials. It serves as an all-in-one testing tool for laboratories and production workshops.

Safe & Stable, Durable

The main body is made of high-strength cold-rolled steel sheet with anti-rust spraying. The temperature control system is equipped with over-temperature protection to ensure operational safety. Accessories (such as steel balls and indenters) are made of wear-resistant alloy to extend the service life of the equipment.
