Spark Testers
On-line Detection of Faults

Spark Testers from Beta LaserMike provide on-line detection of faults in cable insulation, such as voids and pin holes. All Spark Testers are height-adjustable and floor mounted for easy placement in line. Standard models are available for a variety of applications, including high-frequency models for higher line speeds. Spark Testers can be controlled via the SI900 spark tester indicator with standard RS-232 communication and built-in I/O, or via a Profibus interface module. Beta LaserMike offers both standard and high-frequency models to meet your unique measurement needs.
