Multi-functional modules design, defines your combination of solution

MultiPRO delivers ACW, DCW, IR, Continuity multi-functional modules. Mix-and-match your best solution according to your needs.

EEC legacy safety specification now in smaller and flexible packages

Same output deliverable as legacy EST-300 series high performance tester is now in multiple and flexible module, fulfilling different industries and application needs.

Superior Testing Speed

Every second counts on production lines. Shorter test duration means higher production output and more profit. MultiPRO’s unique design enhance both test initialization and step linkage speed resulting in 42%* reduction in overall testing time.

Up to 100 channel synchronized testing

Connect a maximum of 10 systems to perform simultaneous and synchronized electric testing. Optimizes overall testing speed.

Single/dual channel independent module design

This series adopts a fully isolated and independent channel design to ensure the highest stability of the system and minimizes the interference between channels.

Simplifies spare parts demand, no need to purchase the entire system. Easy on production maintenance

The fully modular design greatly reduces maintenance and spare parts costs. Quickly swap the back-up module to minimize production downtime.

Independent test result identification

Test results from each channels can be identified independently, reducing errors and boosting production efficiency.

Optimized Thermal Efficiency

Temperature is the key to system stability. Poor fan ventilation often cause overheating issue. MultiPRO’s unique mechanical and independent fan design allows efficient ventilation. Smart fan management further delivers cool, stable operation and quietness inside.

Simple and intuitive operation

The built-in processor allows scan and collects data directly without connecting to a computer. Less is more.

EEC proprietary ARC detection

Consolidated 40 years of experience in forming a unique ARC detection function that ensures peak quality assurance applies across your products.

Same in Performance, Smaller in Size

Offering the same amount of channels while taking up way less the space, MultiPRO can help improving space utilization. Approx. 60% size reduction
