The IP2X test probe (Test Probe B) is a standardized articulated finger designed to verify protection against accidental contact with hazardous live parts by human fingers. It complies with international safety standards including IEC 61032 Figure 2, GB/T 4208 (IP2X), and end-product safety requirements for household appliances, plugs, sockets, and IT equipment. Equipped with an optional calibrated 10 N ±1 N push force mechanism, it ensures repeatable, compliant accessibility testing during safety certification.
The IP3X and IP4X test probes are precision safety inspection tools designed to verify the ingress protection (IP) rating of electrical enclosures against solid objects, in accordance with international standards such as IEC 60529, IEC 61032, GB/T 4208, and GB/T 16842. These probes simulate real-world access attempts by fingers or wires to ensure hazardous parts remain inaccessible—critical for compliance with safety regulations in lighting, audio/video, household appliances, and industrial equipment.
The KDGK-703S is a high-accuracy, multifunction calibrator designed for the verification and calibration of digital multimeters (up to 4½ digits), analog panel meters (class 0.2 and below), and general-purpose test instruments. Featuring closed-loop digital control, wide output ranges, and ultra-low distortion, it serves as both a standalone calibration source and a precision reference when paired with higher-grade standard meters (e.g., class 0.1+).
The KDJB-430A is a lightweight, high-performance relay protection tester that combines advanced power electronics with high-fidelity linear amplifiers in an ultra-compact form factor. Featuring a 10.5-inch HD touchscreen, dual-core DSP processing, and robust AC/DC output capabilities, it delivers laboratory-grade accuracy for on-site testing of protective relays—ideal for field engineers seeking portability without compromise.
KDGK-500Z AC/DC Circuit Breaker Coordination Tester is a portable, intelligent field instrument designed for on-site verification of protective device coordination in AC and DC power systems. It ensures reliable selective tripping between upstream and downstream breakers in substations and industrial facilities, enhancing system reliability and grid safety—ideal for maintenance teams performing compliance checks on protection hierarchies.
The KDWJF-30kW is a high-performance, low-noise variable frequency power supply delivering a pure sine wave output with ultra-low partial discharge (<5 pC). Designed for precision high-voltage testing, it ensures waveform fidelity, stable frequency control, and reliable operation under demanding laboratory or field conditions.
The KDZD1256 is a high-precision test system designed for comprehensive verification and calibration of integrated primary-secondary fusion equipment such as pole-mounted switches and ring main units. It ensures compliance with national and industry standards, enhances product reliability, and supports efficient grid entry certification.
