Labmate Oil Tan Delta Tester measures dielectric loss factor, relative permittivity, and DC resistivity of insulating oils across a 0–125°C temperature range.

AC test voltages of 500–2200 V with induction heating determine dielectric loss at ±(1% + 0.0001) accuracy, supporting transformer oil aging and contamination assessment.

Manufactured for power systems, substation maintenance, and electrical laboratories performing insulating fluid dielectric loss analysis. IEC 60247 compliant.
