We can build measurement systems that are insulated by light between input and output, allowing you to measure waveforms at high voltages with confidence.


  • Contribute to measurement safety in high voltage environments
  • High-quality floating measurement is possible with excellent common mode removal performance
  • Extremely effective for noise tolerant measurement
  • Compatible with a wide range of applications such as lightning surges and charging tests
  • Remote point measurements (switches, transport equipment, etc.)
  • Failure cause analysis when an abnormal location occurs in a remote location
    (Up to four isolation units can be installed separately)
