A flash tester, also known as a hipot tester, breakdown tester, or dielectric breakdown tester, is used to evaluate whether the insulation of electrical equipment can withstand its maximum working voltage. This ensures electrical safety and compliance in manufacturing and testing environments.

Calibrationhouse calibrates a wide range of flash testers, including multifunctional models that incorporate insulation resistance and earth bond testing. We work closely with GMC Instruments Partner, Seaward Group, whose HAL series testers are widely used in manufacturing and quality assurance.

Flash testers operate at high voltages, making precise calibration essential to ensure measurement accuracy and operator safety. Incorrect readings could lead to faulty insulation verification, increasing the risk of electrical hazards and equipment failures.

Yes, Calibrationhouse provides on-site calibration services across the UK, ensuring that flash testers remain compliant with safety and quality standards while minimising downtime. Customers can also send their devices to our Durham-based laboratory for calibration to the highest UKAS standards.

For customers in the United States, flash tester calibration is available at our Tampa facility, ensuring compliance with BSI ISO 9001-certified standards.

Seaward Group recommends annual calibration for flash testers to maintain accuracy and compliance with industry regulations. More frequent calibration may be necessary in high-usage environments.

To arrange calibration, contact Calibrationhouse via phone, email, or our online request form. Our team will guide you through the process and recommend the best calibration option based on your requirements.
