Insulation Resistance Meter (20kV 20TΩ)
General Information:
EPR50X Intelligent insulation resistance meter also known as megohmmeter, high voltage insulation resistance tester, etc., EPR50X has 7 ranges: 500V, 1000V, 2500V, 5000V, 10000V, 15000V, 20000V, the maximum test can reach 20TΩ, and the manual voltage regulation function.
Features:
● Designed in strict accordance with safety standards
● Insulation resistance range 20TΩ@20kV
● The short-circuit current can be adjusted, up to 5mA (up to 10mA short-circuit current products can be customized).
● Automatically display the test values of polarization index (PI) and dielectric absorption ratio (DAR), which can test leakage current and capacitance.
● Excellent anti-interference performance, when the interference current reaches 2mA, the instrument still guarantees the test accuracy.
● The capacitive test product discharges quickly. When the cable is tested, no manual discharge is required, and the instrument automatically discharges quickly.
● 2 power supply methods: use lithium-ion battery to supply power, and the battery life can reach 4 hours (when 20000V is empty).
At the same time, it can be charged in use. When the power fails, it can automatically switch from AC power supply to battery power supply.
● All English display, English prompt operation, simple and clear, and can display the insulation resistance simulation column.
● Digital filter function, use the filter function to reduce the influence whenever the display value deviation caused by external influence.
● Complete protection function, and equipped with fuse blowing prompt function.
