Product Description

 Model: AUTO-LDA/AUTO-FLD (without chamber)


Standards:IEC60112, IEC 60065, IEC 60238, IEC 60309-1, IEC 60320-1, IEC 60335-1, IEC 60598-1, IEC 60669-1, IEC 60670,IEC 60730-1, IEC 60745-1, IEC 60884-1, IEC 60947-1, IEC 60950, IEC 61058-1.



1)Profile: It is used to evaluate the resistance tracking performance of solid insulating material surface under the combined influence of electric field and humid or contaminate medium. Sum up,it is used to measure the compare tracking index (CTI) and electrical resistance index (PTI).


2) Specification: This IEC60112 Electronic product electrics leakage Tester is a fully automatic instrument contained in its own cabinet to maximize the safety of the operator and mainly used test the resistance Tracking Performance of solid electrical insulation materials when they are exposing in electric affect impurity water situation.Mainly used for determination PTI and CTI items.


Inside the well lit cabinet, a test specimen is placed on a glass plate and two platinum electrodes are lowered on the top surface.


A gauge block is supplied with the instrument to ensure the electrodes have the proper distance between them. The table height is easily adjustable to ensure the proper angle of the electrodes and height of drops. The rest of the test is controlled from outside the test chamber with the door closed.



The voltage,limiting current, drip rate and number of drips are all set on the control panel. An operator should observe the test to see if a flame ignites. The instrument sounds an alarm if there is a tracking failure of at least two seconds.
