Three In One Tester
Consists of a TAPARIA® Line Tester and an easily attachable extension cord with a Test Probe. Easily checks ‘live’ or Neutral wire, continuity or break in circuit. Identifies two different phases. Ideal for domestic use.
In phase line where board is open lamp hold will not work at 440 V bulb will be damaged where as 3 in 1 tester will indicate this different phase of 440 V by glowing more brightly.
