Chroma 19055 Hipot Analyzer: AC/DC/IR Testing with Guardian 500VA, RS-232, USB

Chroma 19055 – Hipot Analyzer (AC/DC/IR) – Guardian 500VA Plus.

The Chroma 19055 Guardian 500VA Plus is a high-performance hipot tester offering AC, DC, and insulation resistance (IR) testing up to 6kV. With a robust 500VA output capacity, it’s engineered for precision electrical safety testing, including corona discharge detection (CDD), flashover detection, and advanced analysis functions such as Discharge Level Analysis (DLA). The floating output design ensures full compliance with EN50191 safety standards, providing optimal protection for operators and devices under test.

This model is ideally suited for industrial applications requiring reliable high-voltage testing and analysis in R&D labs, production lines, or third-party calibration service centers.
