Multifunction Tester


萬用測試儀



Model : MFT1710


 

The MFT1710 series is a range of 4 instruments for testing low

voltage electrical installations to BS7671. They provide all the

tests required to complete the necessary electrical certification

for industrial, commercial and domestic fixed wiring installations.
