Surface Insulation Resistance Testing
AutoSIR2+ - SIR Testing

Following over 2 years of intense research and development, we are proud to introduce the next generation of equipment used to measure changes in Surface Insulation Resistance.

The new AutoSIR2+™ system represents a dramatic improvement over existing SIR test alternatives, and its shielded precision electronics allows state-of-the-art accuracy resistance measurements to be made up to 1014 Ω.

One AutoSIR2+ chassis can hold between 1 to 16 measurement cards and can monitor up to 256 x 2-point test patterns or 78 x 5-point test patterns, or 32 x 9-point test patterns at selectable intervals from minutes to days. Each channel is current limited (1 M Ω), ensuring that dendrites are preserved for failure analysis. The frequent monitoring capability provides a full picture of the electrochemical reactions taking place on a circuit assembly, and provides early trend analysis enabling tests to be curtailed, thus saving considerable test time and money.

Key Features
