Consistent UV light curing requires periodic monitoring of UV intensity or dose. The ACCU-CAL™ 50 radiometer is simple to operate and offers repeatable measurement of UV light. The ACCU-CAL™ 50 can measure UV light emitted from lightguides (3 mm, 5 mm, and 8 mm), UV flood systems, and UV conveyors. With a spectral sensitivity from 320 to 395 nm (UVA), the ACCU-CAL™ 50 measures intensities from 1 mW/cm2 to 40 W/cm2. A specially designed photo-sensor assembly protects the photo-sensor from the high temperatures sometimes associated with today’s high intensity UV spot lamps.

Complete radiometer with lightguide adapters (3 mm, 5 mm, and 8 mm) and lightguide simulator (A lightguide simulator is used to measure direct spot lamp intensity (required to calculate lightguide transmission); includes storage/carrying case.

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™ 50 radiometer annually to ensure proper operation of the instrument. Calibration services are available through Dymax®.

Three Reasons to Use a Ultraviolet (UV)/Visible Radiometer

Three Reasons to Use a Ultraviolet (UV)/Visible Radiometer

 N/A
  • Maintaining a Light-Curing Process - A radiometer measures whether a light-curing system is providing intensity above the "bulb change" intensity. Radiometers provide the same monitoring control for light curing processes that thermometers provide for thermal processes.
  • Providing a Worker Friendly Light-Curing Process - The ACCU-CAL™ 50 is sufficiently sensitive to measure the intensity of stray or reflected UV light (as little as 1 mW/cm2). Dymax® recommends that worker UVA exposure not exceed 1 mW/cm2. For reference, UV (320 to 395 nm) intensity on a sunny day can range from 2 to 6 mW/cm2.
  • 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 resin below the intervening substrate.
