HIOKI Insulation Tester ST5520

The Hioki PW3360 Clamp On Power Logger is a crucial tool in the field of electrical safety testing, specifically designed to ensure the insulation resistance and voltage withstand capabilities of electrical devices and components. This device aligns with various safety standards, making it an indispensable asset in quality assurance and regulatory compliance.

Industry-Leading Speed and Accuracy

The Hioki PW3360 sets itself apart with its remarkable speed, capable of delivering pass/fail assessments in as fast as 50 milliseconds. This rapid assessment capability ensures that production lines can maintain high throughput without compromising on safety or quality.

Advanced Safety Features

Equipped with a quick discharge feature, the Hioki PW3360 efficiently dissipates residual voltage, enhancing safety for both the device and the operator. This feature is particularly important in environments where multiple tests are conducted successively, such as in mass production settings.

Versatility and Precision in Testing

The PW3360 offers a freely configurable test voltage, allowing users to set voltages from 25 V to 1000 V with 1 V resolution. This flexibility ensures that the tester can be adapted to a wide range of standards and specifications required for various products and components.

Enhanced Reliability with Built-In Checks

The device includes a crucial contact check function, which prevents errors due to poor contact between the tester and the device under test. This feature helps to avoid false readings and ensures that only accurate data is recorded. Additionally, the short-circuit check function acts as a critical safeguard, stopping potential defects from reaching the market by identifying them early in the testing phase.

Ideal for High-Stakes Production Environments

The Hioki PW3360 is particularly well-suited for battery production lines, where the reliability and safety of each unit are paramount. The tester’s capabilities make it an ideal choice for ensuring that all battery units meet stringent safety criteria before they are shipped out.
