Uni-T UT526 Insulation Earth Electrical Tester Meter


UT525/UT526 is a digital multi-functional electric testing instrument adopting
new design and integrating large scale analog integrated circuit, digital circuit
and microprocessor chips, which can mainly test parameters of residual current
device (RCD), earth, insulation resistance, DCV and ACV; with features of full
functions, high accuracy, stable performance, easy and reliable operation, it
is available to test RCD, insulation and earth of electric equipments. UT525/
is the ideal selection for repairing, maintaining and testing RCD of all
electric equipments.
