SIR

Surface Insulation Resistance Testing
GEN3

The world’s most trusted, versatile, and high-performance SIR tester

The AutoSIR2+™ has evolved into the world’s best-selling SIR tester, trusted by industry leaders for unmatched reliability and precision.

Offering measurements up to 10¹⁴ Ω, it features advanced multibias capability, enabling testing with up to three different bias voltages in a single run for maximum versatility. Available in 64, 128, and 256 channel configurations, it supports parallel PCB testing to boost throughput and reduce testing time.

Customisable racks and real-time monitoring provide early trend analysis, saving time and costs. With user-friendly software, testing intervals as short as 1 minute, and high-voltage testing, the AutoSIR2+™ sets the standard for high-performance SIR testing.

GEN3 offers custom Test Racks as accessories to the AutoSIR2+ & CAF2+.

Our customisable test racks are designed to facilitate and streamline the SIR & CAF testing process. These test racks are engineered to accommodate multiple printed circuit boards (PCBs) or electronic assemblies for simultaneous testing, making the process more efficient and cost-effective. We can design our test racks around ANY test coupon or assembly and can work with you to design your own coupons for your own manufacturing requirements.

Our test rack can offer you:

  1. Flexibility: The test racks are designed to be highly flexible, allowing for easy customisation to meet the specific needs of different PCB sizes, shapes, and configurations. This adaptability ensures compatibility with a wide range of electronic components and assemblies.
  2. Multiple Testing Ports: Our racks typically have multiple testing ports, enabling parallel testing of several PCBs/ simultaneously. This feature significantly increases testing throughput, reducing the time required for SIR testing.
  3. Rain Guard: All of our racks come with a rain guard in case the environmental chamber has an issue where 'rain' occurs. The rain guard protects your assemblies from direct droplets. 
  4. Precise Test Point Access: Our test racks are designed to ensure precise and reliable contact with the PCB's test points. Proper contact is critical for obtaining accurate SIR test results.
  5. User-Friendly: Our test racks are designed to simplify the setup and operation for SIR/CAF testing, making them accessible to operators with varying levels of expertise.
