Product Update


We now offer the AccuMAX XRP-3000 with a sensor front end aperture of 0.5” in diameter to address the new meter requirements of E3022 for LED UV Lamp measurements. The new sensor option is functionally the same as the XRP-3000. For purchasing select PN: UV-SP-XRP-3000A


  • Microprocessor-controlled readout unit with dual-wavelength sensor detector
  • Superior bandpass interference filter
  • Choice of direct or USB connection between sensor detector and readout unit
  • Excellent cosine response
  • User-selectable, multilingual display settings. Choose from English, French, German, and Spanish
  • Large, easy-to-read LCD screen
  • Sealed sensor housing and USB connection with water-resistant adapter


Featuring automatic zeroing, integration and signal hold, the unit provides accurate readouts for UV, visible irradiance or radiance. The LCD readout features ±0.2% linearity with the sensor sending the linearity correction data to the readout unit during initial power up. To ensure consistent results, sensors are designed with superior bandpass filters while optical stacks are assembled in Class 100 clean workstations. For precise spectral coverage, high-quality interference filters are used to resist degradation.



The rugged meter housing features a removable, rubber protective boot for better grip and to help prevent accidental breakage. It also provides superior protection against moisture contamination, shock and humidity. In addition, the XRP-3000 features a liquid and water resistant sealed sensor housing with a special self-sealing ring to help eliminate light leakage.

Simple Operation

The XRP-3000 meter’s microprocessor is the heart of its simplicity. Just four pressure-sensitive buttons on the readout unit’s membrane keypad offer an extensive array of advanced functions. For example, to subtract ambient light, the user need only press the “ZERO” button. This activates autozeroing, sets the value to 0 and displays relative readings of subsequent measurements. “HOLD” freezes the display thus obtained, while “INTG” displays the average UV intensity after integrating the UV energy over time. These functions and other user-selectable parameters are easily accessible through the software’s main and sub menus.


Multilingual Display Settings

The XRP-3000 features user-selectable, multilingual display settings. Choose from four languages: English, French, German, and Spanish.

The XRP-3000 radiometer is carefully quality-controlled to ensure that each unit has up-to-date calibration and meets stringent measurement requirements. Housed in a durable polycarbonate case, it features dependable solid-state electro-optical circuitry for long, trouble-free operation.



The XRP-3000 is compact, lightweight and battery-operated for convenient use in the factory, field or any other location where measurements need to be taken. A slide-out panel allows for easy replacement of the unit’s 9-volt batteries.


AccuMAX XS-555/L Luminance Sensor Detector

The perfect accessory for the AccuMAX Series meter. Ideal for technicians performing radiographic examinations. Meets ASTM E1742 standard.

Luminance is typically used to measure uniformly radiating surfaces, such as backlit panels, film viewers and monitors. The AccuMAX XS-555/L luminance sensor detector measures the brightness of a visible light source and, unlike many competitive units, allows the user the choice of displaying the results in three distinct units of measure: candelas per square meter (cd/m2), candelas per square foot (cd/ft2) and footlamberts (fL).


Sensor Guard Upgrade

Spectro-UV now offer an optional Sensor Guard into the XS-555/L Luminance Sensor Detector. This Sensor upgrade is perfect for technicians using the XS-555/L for testing of Computed Radiography (CR) Monitors In Accordance With ASTM-E-2033-17 Paragraph 6.1.8. The upgrade enhances the performance of the sensor while taking monitor readings.

The inclusion of the Sensor Guard provides key advantages:

  • Enhanced Performance: The Sensor Guard provides for even more accurate and reliable readings ensuring optimal performance. The Sensor Guard provides for a tighter seal against ambient light. Decreased ambient light reduces the variability of readings, especially relative to the low contrast resolution readings.
  • Surface Protection: The Sensor Guard acts as a softer interface between the sensor and the monitor and reduces the likelihood of scratching.
