The gauge of dielectric strength 3173 - this is portable, compact instrument for checking dielectric strength of isolation (insulation test at the point of the breakdown).

• Presence of external entrance and output for the remote control besides instrument.
• Testing dielectric strength to 3 kV (ACE 3000 c)
• Functions of comparator (PASS, FAIL).
• Checking contacts and wires of high voltage for obtaining the reliable test results (possibly only with the use of an option the 3931- tester of the contacts of high voltage)

Options:
3931 testers of the contacts of the high voltage (it is used for the checking of stress beyond different connections (clamps) of the [testiruemoy] chain. The reliability of the results of testing ensures. Often test results are incorrect because of the poor contact or the damaged wire)
