The AutoSIR2+ has evolved into the world’s best-selling Surface Insulation Resistance (SIR) test system, trusted by industry leaders for its reliability and precision.

The system supports measurements up to 10¹⁴ Ω and features advanced multibias capability, allowing testing with up to three different bias voltages in a single run. It is available in 64, 128, and 256 channel configurations, enabling parallel PCB testing to improve throughput and reduce overall testing time.

Customisable racks and real-time monitoring enable early trend analysis, contributing to time and cost efficiency. With user-friendly software, testing intervals as short as 1 minute, and high-voltage testing capability, the AutoSIR2+ defines the standard for high-performance SIR testing.
