Introducing UV LED Test Dosimeters

A Simple Way to Verify Curing Performance

Alpha-Cure has expanded its range of accessories with the launch of UV LED Test Dosimeters—a practical tool that helps press operators, maintenance teams and process engineers monitor UV LED system performance quickly and accurately. In this blog, we explore what these dosimeters do, how they work, and why they’re a smart addition to your LED UV curing toolkit.

Why Test Dosimeters Matter

In UV LED curing applications—whether in printing, bonding or coating—consistency is critical. Over time, UV LED systems can experience performance degradation due to contamination, optical issues, or system wear. While traditional power meters offer detailed data, they can be expensive, require calibration, and aren’t always practical for day-to-day checks on the shop floor.

That’s where UV LED Test Dosimeters come in.

These simple, adhesive-backed test strips change colour in response to UV exposure at the specific LED wavelength of 395nm. With a visible colour shift that correlates to a known dose range, they provide an instant and reliable indication of whether your system is delivering sufficient energy for effective curing.

Key Features

• Wavelength Compatibility: 395nm UV LED sources

• Visual Feedback: Colour changes visibly to indicate UV dose levels

• Quick Checks: Use during routine maintenance, lamp changes or process troubleshooting

• No Tools Required: No need for radiometers or specialist equipment

• Compact & Disposable: Easy to store, easy to use, no clean-up

Practical Use on the Production Floor

UV LED Test Dosimeters are ideal for:

• Daily system checks – Ensure UV LEDs are functioning as expected before starting a job

• Troubleshooting – Quickly identify whether poor cure results are UV-related

• Process validation – Compare dosimeter results between curing stations or over time

• Preventative maintenance – Monitor changes in UV output before it affects product quality

With a small investment in dosimeters, teams can avoid costly downtime, reduce waste and maintain process quality—especially useful in high-volume or high-spec applications.
