  • Benefits

  • PowerMax-RS provides RS-232 conncectivity. Power input provided via +5 VDC input from external power supply or through Pin 1 on RS-232 connector.
  • Instrumentation platform is compatible with thermopiles and optical sensors and can be adapted to most power sensors that Coherent manufactures.
  • Displays beam position with position-sensing quadrant thermopiles (with LM-model sensors like LM-10).
  • High resolution 24-bit A/D converter supports four digits of resolution and measurement accuracy equivalent to that found in Coherent's LabMax meters.
  • Spectral compensation is unique to each device for improved accuracy.
  • Long-pulse joules capability with thermopile sensors.
  • NIST traceable measurements.
