ST5520
ST5520
Hioki
Insulation Tester
Industry's Fastest Insulation Tester Assesses in as Fast as 50 ms
The Hioki electrical safety testers are designed for insulation resistance and voltage withstand testing of electrical devices and components according to various safety standards. The ST5520 is the fastest insulation tester in the industry, delivering pass/fail assessment in as fast as 50 ms. 25 V to 1000 V test voltage with 1 V resolution.
Key Features
- Rapidly assess in as fast as 50 ms
- Quick discharge of residual voltage
- Freely configurable test voltage (set from 25 V to 1000 V, 1 V resolution)
- Contact check function (prevents errors due to poor contact)
- Short-circuit check function (stops potential defects from reaching the market)
- Ideal for battery production lines
