Product Introduction

        This Insulating Oil Dielectric Strength Tester is a high-accuracy, fully digital industrial instrument developed by our company's entire research and technical team. Based on the national standard GB507-86 and the industry standard DL/T846.7-2004, we leveraged our strengths and conducted numerous field tests and long-term efforts to create this device. It is easy to operate and features an aesthetically pleasing design. Thanks to fully automated digital microcomputer control, it offers high measurement accuracy, strong anti-interference capability, and safety reliability.

Product Features

☆ The instrument uses a large-capacity single-chip microcomputer for stable and reliable operation;

☆ It features temperature and humidity display, clock function, and a ground alarm to remind users of safety;

☆ Equipped with a wide-range watchdog circuit to prevent crashes;

☆ Multiple operation options: the program includes two national standard methods, GB1986 and GB2002, as well as custom operations to meet diverse user needs;

☆ The oil cup is made of special glass through one-time casting, eliminating oil leakage and other interferences;

☆ Unique high-voltage end sampling design allows test values to go directly into the A/D converter, avoiding errors in analog circuits for more accurate measurements;

☆ Built-in protection against overcurrent, overvoltage, short circuits, etc., with strong anti-interference capability and excellent electromagnetic compatibility;
