Labmate Oil Tan Delta Tester offers wide measuring range of 5 to 200 pF. They feature three-electrode oil cup with 2 mm spacing to reduce leakage and stray capacitance interference. Their smart sensors issue warnings for overheating, disconnection, or sensor malfunction. These perform automatic empty cup calibration to confirm proper cleaning and alignment before each test. Our Oil Tan Delta Tester is applied to measure dielectric loss and resistivity of insulating oils in power systems and laboratories.
