• Kewtech KTD40

Key Benefits:

  • Great value for money, great specification in a hand held style of case 
  • High current loop test actually reads true loop impedance instead of loop resistance - beneficial when measuring Ze near a transformer
  • Low current loop test for bypassing both passive and electronic RCDs 
  • The KTD40 uses the very latest in electronic design to produce a compacy and feature packed test instrument. For instance, it included a full socket tester that will check for 18 socket wiring conditions. It will also check for the very hazardous condition of a reversal of line/neutral at the supply 
  • This instrument is capable of measuring true loop impendence. This gives more relevant information when testing PSC/PFC as the reactance of the suppliers transformer is measured as well as the pure loop resistance. 
  • With the optional distribution board test lead set, a high current two wire test can be carried out.
  • PFC or PSC is displayed after a loop test has been carried out, it is shown instantly after the press of a second button to change the display. 

Key Features:

  • Low current - non trip - and high current loop impedance (Patented) 
  • High current test reads true loop impedance (incl. the suppy transformer's reactance) 
  • Full socket tester functionality built in 
  • Unique mains supply polarity test (checks that line and neutral are not switched at the supply)
  • Instant readout of PFC/PSC by means of a secondary button 
  • Voltage test function L-N, L-E & N-E
  • Fully protected agains accidental phase to phase connection 


  • KAMP13 - Mains Test Lead Only 
  • Certificate of Conformity 


  • ACC016E - Distribution board test leads
