Tracking Tester is designed and manufactured according to the standard requirements of IEC60112. This device is used to measure the Comparative Tracking Index (CTI) and Proof Tracking Index (PTI).
Tracking Tester Features:
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.
