Items	39561 ACCU-CAL™ 50 Ultraviolet (UV) Intensity Meter Radiometer for Flood Lamps and Conveyors	39560 ACCU-CAL™ 50 Ultraviolet (UV) Intensity Meter Radiometer for Spot and Flood Lamps and Conveyors
Description	N/A 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 (without lightguide adapters or 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	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.
