Simplify Validation and Monitoring of Your UV Light-Curing Process

Consistent light curing requires periodic monitoring of light intensity or dose. The ACCU-CAL™ 160 radiometer is available in both a UV and LED model and can measure UV & LED light up to 10 W/cm2 emitted from stationary light-curing flood lamps or lamps used in conveyorized processes. This radiometer can be used to determine intensity (measured in mW/cm2) or total energy as derived from intensity and exposure time (measured in mJ/cm2). When compared to the ACCU-CAL™ 150 radiometer, the ACCU-CAL™ 160 offers a number of improved features and benefits including a longer calibration cycle (12 months instead of 6), an easier-to-use set-up screen, and a graphical display that is clearer and easier-to-read. The unit is simple to operate and can be controlled manually via four buttons on the faceplate or by a USB remote interface.

Dymax® ACCU-CAL™ Radiometers

N/A Dymax® offers ACCU-CAL™ radiometers for spots, floods, and conveyors. Kits for spot lamps include the complete radiometer with 3, 5, and 8-mm lightguide adapters and a lightguide simulator. Adapter kits are available separately for users who have an existing flood/conveyor kit and need to use it for spot systems. All radiometer kits include a storage/carrying case. ACCU-CAL™ radiometers are calibrated to measure either UV-A (320 to 390 nm), LED (~ 350 to 450 nm), or visible (395 nm to 465 nm) light intensity.

Radiometer Calibration

N/A Dymax® recommends calibrating the ACCU-CAL™ 160 radiometer every 12 months to ensure proper operation of the instrument. Calibration services are available at Dymax®.

Reasons to Use a Radiometer

N/A

  • Validating and Maintaining a Light-Curing Process - A radiometer provides a quantifiable measurement that verifies if the light-curing process is operating within the qualified parameters. Since all UV bulbs degrade over time, the radiometer will reveal the optimal time for bulb replacement in an UV light-curing device. Radiometers provide the same monitoring control for light-curing processes that thermometers provide for thermal processes.
  • Measuring Transmission Rates Through Substrates - A radiometer can be used to measure the transmission rates of various wavelengths through substrates that sometimes absorb various frequencies of energy. To assure an effective curing process it is critical to measure the light intensity reaching the cure site below any intervening substrate.

Features

N/A

  • Clear, Easy-to-Read Graphical Display
  • For Use with Flood Lamp or Conveyor Systems

Additional Information

N/A A data download kit is included with each radiometer at no charge and downloads easily into Microsoft Excel.

Measurement results are displayed on the integrated LCD display or transmitted by the USB remote interface to a computer.

Radiometers measure the intensity of energy at specific wavelengths. UV light is, by definition, not visible to the human eye, so a radiometer is required to determine the amount of UV energy. The ability to measure light intensity is useful for three reasons:

  • Maintaining a light-curing process - A radiometer can measure whether a light-curing system is providing intensity above the "bulb change" intensity. A radiometer is to a light-curing process what a thermometer is to a heat-curing process.
  • Providing a worker-friendly light-curing process - A radiometer is required to determine if any UV light is reaching operators or bystanders.
  • Measuring transmission rates through substrates - A radiometer can be used to measure the transmission rates of various wavelengths through substrates that absorb UV and/or visible light. To assure an effective curing process it is critical to measure the light intensity reaching the light-curable material below the intervening substrate.
