Mar.25.2026—EEC Huayi, a leader in electrical safety testing for nearly 50 years, has officially launched two new essential testing instruments: the EEC-31 (3-in-1) Hipot Tester and the EEC-41 (4-in-1) Hipot & Ground Bond Tester.
Built on decades of application experience, these models are designed to meet the core needs of manufacturers in real-world production and inspection environments. By integrating multiple functions into a single unit, the EEC-31 and EEC-41 deliver a stable, all-in-one solution that emphasizes both operational reliability and cost efficiency.
"With the launch of the EEC-31 and EEC-41, we are directly responding to the market's need for reliable, high-precision equipment that remains accessible," says Shannon Sivak, Global Sales Director. "By consolidating multiple testing functions into these two versatile models, we’ve created a solution that is competitively priced, ensuring manufacturers can scale their testing capabilities and meet safety standards without exceeding their budgets."
EEC-31: Efficient 3-in-1 Testing in a Compact Design
The EEC-31 model integrates AC Hipot, DC Hipot, and Insulation Resistance testing into a single unit, purpose-built for production-line applications across a wide range of industries. Featuring a rotary knob interface, parameter setup is intuitive and easy to learn, enabling operators to get up to speed quickly. This reduces training time while simultaneously improving overall testing efficiency.
In terms of performance, the EEC-31 supports insulation resistance measurements up to 200 GΩ at 4 KV, meeting high-resistance testing requirements for electronic components, electric vehicles, and battery manufacturing. An optional USB interface is also available, allowing for straightforward data acquisition and integration with automated testing environments.
EEC-41: 4-in-1 Testing to Meet Broad Regulatory Requirements
Building on AC Hipot, DC Hipot, and Insulation Resistance testing, EEC-41 further integrates AC Ground Bond testing, delivering comprehensive 4-in-1 electrical safety testing capability. With an 500VA AC hipot and 32A AC ground bond test support , the EEC-41 is well-suited for applications that demand higher grounding current and superior test stability.
Designed with a clean layout and clear parameter-setting logic, the EEC-41 balances ease of operation with strict regulatory compliance. In addition to front-panel operation, the instrument supports PLC remote control. An optional USB interface enables seamless integration with automated production lines and test systems, making the EEC-41 ideal for large-scale, multi-industry applications.
Quality and Service Assurance
Both the EEC-31 and EEC-41 are built on proven, reliable design architectures. All models are shipped with test leads and factory test reports as standard. To ensure long-term peace of mind, both models come with a global warranty, ensuring customers receive consistent technical support and dependable after-sales service worldwide.
The launch of these models further expands EEC Huayi’s portfolio of multifunction safety solutions. Looking ahead, EEC-Huayi continues to advance product development to help manufacturers enhance quality management while confidently meeting increasingly stringent electrical safety compliance requirements.
