Description
SM7810 Super Megohm Meter for Rapid Multi-Channel Testing
The SM7810 Super Megohm Meter from Hioki is an advanced 8-channel insulation resistance tester designed for precise and high-speed leakage current testing, particularly for multi-layer ceramic capacitors (MLCCs). With its ability to measure extremely low currents (1 pA) up to 1 mA and a wide resistance range of 1×10² Ω to 1×10¹⁵ Ω, the SM7810 ensures accurate detection of even the smallest insulation faults in production lines.
Engineered for speed, the SM7810 performs parallel 8-channel measurements in just 6.8 ms, making it ideal for mass production testing. Multiple measurement speed options (FAST, MED, SLOW, SLOW2) allow customization based on the application. Its channel-independent contact check function guarantees consistent testing by detecting poor connections or improperly seated components, reducing errors and improving production reliability.
The instrument’s flexible design supports external voltage input from 0.1 V to 1000 V, making it suitable for various MLCCs and electronic components. Individual channel settings enable users to create optimized testing sequences and integrate the device seamlessly into automated inspection systems. The SM7810 also includes essential features such as trigger delay, averaging, jig capacity correction, measured value comparison, and jig resistance open correction, ensuring precise and repeatable results.
Connectivity options such as GP-IB, RS-232C, and EXT I/O allow integration into fully automated testing environments. With its compact size, 10.5 kg weight, and included accessories like the voltage input connector and power cord, the SM7810 is production-ready and built for continuous operation.
Ideal for manufacturers of MLCCs, high-voltage electronics, and R&D labs, the SM7810 Super Megohm Meter combines speed, accuracy, and reliability for efficient and high-precision insulation testing.
