Spark Tester Calibrator

Spark Tester Calibrator

For Spark Testing with constant and comparable sensitivity on insulating, winding and sheathing lines, it is very essential to calibrate the spark tester with a spark tester calibrator.

Kat Controls make Spark Tester Calibrator Model STCAL-2K is designed to meet the requirements of relevant Indian and international standards for Spark Testers. One can measure the test voltage and it’s frequency with the help of Spark Tester Calibrator.

Incorporating Digital Voltmeter, this versatile Calibrator is used for both Voltage Calibration and measurement of Fault detection sensitivity of various makes and type of spark testers.
