Earth Resistance Tester

Impulse Winding Tester is suitable for motor ( three-phase machine), transformer, small inductance coil, micro motor and other kinds of wire coil measuring.

Programmable High Voltage - Insulation Resistance Tester MT-9922BXE is the first precision variable frequency withstand voltage and insulation resistance tester in the safety industry. The output AC voltage has a frequency range of 40.0Hz~400.0Hz and a resolution of 0.1Hz. The output voltage adopts hardware feedback, high-speed MCU control technology, and the output voltage regulation rate is within 1%, which can be used not only as a withstand voltage tester, but also as a variable-voltage high-voltage source. The three test modes of AC withstand voltage, DC withstand voltage and insulation resistance can be used in any combination. It is a high-performance instrument used for long-term production line for voltage and insulation resistance testing.

Tangent Delta Tester is applied to measure the dielectric loss and capacitor value of insulation materials in high voltage power equipment. The non-power frequency voltage source is integrated in the tester to avoid power frequency interference. That make the tester has a good performance in measurement precision.
