UV Intensity Labels

UV Intensity Labels for UV Exposure Measurement

The CON-TROL-CURE® UV INTENSITY LABELS™ photochromic intensity indicators are a basic, reliable, low cost, simple, in-house method of monitoring UV intensity. When exposed to UV, the yellow labels undergo a gradual color change from yellow to blue that is directly related to the energy value received.

Made from the same exclusive material as the UV FastCheck Strips™, the The UV Intensity Labels™ (N010-005) have the same colour changing principle as the Strips, but they have only 1 colour changing square. The UV Intensity Labels have a sensitivity range that is perfect for visual inspection of UV energy levels. The UV-C Intensity Labels (N010-004) offer an improved response to the UV-C spectrum, providing a better visual indication for lower power germicidal applications.

The adhesive backed label is placed on a sample product or substrate and processed to proper cure rate. The colour deviation can easily be measured with a spectrophotometer to record colour change or by comparing the colours to test labels created to known operating standards to determine lamp failure or processing inconsistency. NOTE: For best results, observe colour change immediately after exposure to UV light as label may change.

If used on a regular basis, they can detect equipment problems at an early enough stage to prevent lengthy shutdowns. Daily tests can easily indicate a step by step calibration for an accurate reference within each batch. The use of a Digital Tachometer can help insure repeatable results.

Suggested Use: the Con-Trol-Cure® Intensity Labels™ are especially useful in systems where other instruments are not practical, such as 3-D curing, web coating, container printing, medical sterilization, etc.


• The UV Intensity Labels™ measure the entire UV spectrum
• Accurate visual determination of UV dose made possible
• Monitor UV dose in difficult-to-access curing environments
• Detect UV lamp degradation and equipment failures
• Provide the user with periodic assurance that their UV source is performing to expectations
• Greater rate of colour change provides clearer, more precise UV dose determination
• Determine the dose profile in the 3D curing chambers or across wide webs to ensure even cure
• Measure the dose of sunlight in outdoor curing applications
• Evaluate and compare multiple UV light sources
