SKU: N/A Category:

MAY130 Series Optical Power Meter adopts novel and ergonomic desgin, which is durable. The ports of Optical Power Meter and optional Visual Fault Locator adopts embedded detector, which can be well protected.


  • Adopts 1mm large photosensitive surface detector
  • User can customize 50 wavelengths
  • Max/min power tracking
  • Power resolutionand refresh rate are adjustable
  • Data can be uploaded via USB cable
  • Clear dark current
  • User calibration
  • Automatic frequency identification
  • Automatic wavelength recognition

MAY131 Series Optical Light Source can transmit with a wavelength identification digital encrypted protocol, enabling MAY130 Series Optical Power Meter to automatically switch to the proper calibration wavelength. This feature reduces the need for communication between two technicians and decreases the possibility of making mistakes.
