Hi-pot Testers

We have a comprehensive selection of hi-pot testers to meet your safety testing needs.

With over 70 years experience, Seaward have designed and developed a comprehensive range of hi-pot testers which perform AC and DC tests to ensure the electrical safety of your products.

Choose from a basic hi-pot tester such as the Sentinel 200 or a more comprehensive hi-pot tester such as the HAL 104 which performs other tests such as Earth/ground bond, insulation resistance and leakage tests.

If you would like someone to contact you to discuss your hi-pot testing requirements, please get in touch.
