At Zedflo, we supply the MI 3201 Tera Ohm 5 kV Plus from Metrel. It is a portable insulation tester designed to measure insulation resistance by using high DC test voltages up to 5 kV. Tera Ohm 5 kV Plus performs insulation resistance measurements up to 10 T§Ù, step voltage test, withstanding voltage test, polarization index (PI), dielectric discharge (DD), and Dielectric absorption ratio (DAR) calculation and capacitance measurement. Results can be stored and downloaded to a computer via a USB or RS232 connection with the optional PC SW TeraLink Pro. The large LCD screen enables a real-time graph to be displayed.
