Labmate Automatic Oil Dielectric Tester measures insulating oil breakdown voltage at 0–80 kV and 0.5–5.0 kV/s voltage increase rate at ±3% accuracy.

Microprocessor-controlled sequences automate boosting, stirring, and static cycles across 1–10 programmable runs; thermal printer outputs breakdown results with over-voltage protection.

IEC 156, ASTM D1816, and ASTM D877 compliant, manufactured for power utilities, transformer manufacturing, and QC laboratories supporting insulating oil dielectric testing.
