Kewtech KT400 Loop Impedance & PSC / PFC Tester 

Kewtech KT400 is a fully featured single function tester that fits your hand - a great way to go 18th edition testing!

A magnetic hanger is provided enabling you to clip and hang the instrument off any metallic surface and the electronic hands-free feature puts the tester in constant measuring mode.  The tests start when the probes are connected to the circuit under test.  These features together mean that you have your hands fully free to use the probes. Additionally, there is a clip out leg to enable the tester to be freestanding.

A voltage present LED lights up if the test leads are connected to a live circuit. An automatic back-light also operates when testing to help you out in dark environments.

Kewtech small and feature-rich single function testers use the latest in technology to provide a truly viable alternative to a multifunction tester for 18th edition testing. Most of your testing will be catered for by your insulation/continuity tester, your RCD and Loop tester only coming out when power is connected.
