Product Advantages

Equipped with a German-imported Siemens CPU central processing unit, ensuring the highest data acquisition accuracy and stability. It eliminates the interference issues associated with traditional circuit board control systems, which often affect measurement precision and cause frequent system crashes.

Wireless control design eliminates distance limitations and enables human–machine separation, making operation more convenient. This innovative approach also significantly enhances operator safety.

Dual-direction voltage and current interference suppression technology prevents loss of control and communication port damage caused by current interference at the moment of breakdown.

New software with self-diagnostic and early warning functions, featuring dual-direction current and voltage judgment, and supporting wireless safety control.

Built-in leakage protection shield and automatic arc pressure relief system ensure safer operation during testing.

Test electrodes are equipped with a bearing slide rail system, enabling automatic vertical positioning and ensuring accuracy within 0.05 mm.

Compared to other manufacturers whose equipment is limited to solid materials, this tester is capable of testing both solid and liquid insulating materials, offering broader application capabilities.

Built-in fuse protection and leakage protection devices effectively disconnect power under overcurrent or overload conditions, protecting both the control system and high-voltage components. Replacement is simple and convenient.

Test results can be automatically filtered, with selective data retention options.

Remote maintenance and alarm functions enable more efficient after-sales support.

Unlimited storage capacity for test result data.

Software supports wireless cloud protocol upload, allowing third-party data editing and management.
