The Benning IT-120B is a Digital Installation Multifuction Tester which is capable of a full range of electrical testing and can perform insulation resistance tests and loop impedance tests. The loop impedance function on the Benning IT-120B is unlike most other multifunction testers as it can perform this test without the tripping of a 10mA RCD under normal conditions.
Additionally the Benning IT-120B will undertake RCD testing, including trip current and trip time tests, plus phase sequence/rotation and ground resistance tests. The Benning IT-120B is an advanced multifunction electrical installation tester with a host of built in features, making it a valuable addition for testing electrical installations and circuits.
A large illuminated graphic display and built in help function makes this particular unit user friendly. The built in connection diagram assists in ensuring correct connections are made for testing. and the PASS/FAIL indication on the display makes the user's job easy and uncomplicated.
