4324-KT 4334-KT

Thermal Resistance Tester              


The KT series testers measure thermal resistance characteristics of transistors, diodes, MOSFETs and IGBTs.
It can also measure the Safe Operation Area of these devices. Contact check is pretested to ensure precise measurement.
The tester is equipped with device protection circuit to prevent device damage at the start of an avalanche.







♦Multi test function


♦Max 60 test program memory capability


♦Contact check/Short Check


♦Oscillation Detection/Device Protection Circuit


Software Options


♦Test control software by PC


  (Creating test programs, Data collections, counter)


♦Characteristic curve indication software per device.
