  • Large, easy-to-read LCD screen
  • Sealed sensor housing and USB connection with water-resistant adapter


The AccuMAX™ XRP-3000 radiometer/photometer kit uses a dual-wavelength UV-A/VIS sensor detector to measure both ultraviolet and visible light. 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, set the value to 0 and display relative readings of subsequent measurements. "HOLD" freezes the display obtained, while "INTG" displays the average UV intensity after incorporating the UV energy overtime. These functions and other user-selectable parameters are easily accessible through the software's main and sub menus.

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.

The XRP-3000 offers extreme flexibility in the workplace. For technicians performing radiographic examinations, the XS-555/L luminance sensor detector is available as an accessory to provide film viewer output measurements in cd/m², cd/ft² or fL.

AccuMAX™ XS-555/L Luminance Sensor Detector

The perfect accessory for the AccuMAX XRP-3000 Digital Radiometer/Photometer Kit. Ideal for technicians performing radiographic examinations.

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).


  • Meets ASTM and MIL standards.
  • Extremely versatile. Provides luminance measurements in cd/m², cd/ft² and fL.
  • Ideal for radiographic examinations requiring film viewer output measurements.
  • Connects easily to the digital readout unit via a USB cable.

Optional Single-Sensor Detectors

In addition to the dual sensor and luminance sensor detector, individual single-sensor detectors are available to measure UV-A output (XS-365) and visible illuminance (XS-555/I).
