Spectroline AccuPRO™ XRP-2000

Accupro™ Series meters feature an advanced, microprocessor-controlled readout unit calibrated to accurately measure and display UV-A, Blue and visible light readings.

Available in two versions:
The AccuPRO™ (XP-2000) readout unit features a single dual-wavelength sensor detector designed to measure both ultraviolet and visible light.

The AccuPRO™ Plus (XP-4000) features a single 3-in-1 multi-purpose sensor that measures ultraviolet, visible and blue light.

These compact, lightweight, battery-operated units are ideal for use in the field, the factory or anywhere accurate light measurements are needed!

The AccuPRO™ meter features a dual-wavelength UV/visible light sensor.

  • Large, easy to read, LCD screen with 4-digit auto-ranging display
  • Both units provide accurate readouts for UV-A irradiance as well as visible illuminance
  • AccuPRO™ Plus unit also measures BLUE light!
  • Simply to use, three-button interface. Toggle between light measurement modes.
  • Overall accuracy greater than ± 5% per NIST standards
  • Superior band-pass interference filter provides excellent cosine response
  • One-touch PEAK with reset functions
  • User-defined power save and automatic shutoff
  • User-selectable, multilingual display settings at any operational level. Choose from English, French, German, Chinese and Spanish.
  • Rugged meter features protective rubber housing for better grip and to help prevent accidental breakage
