UV Radiometer

High-Performance UV Intensity Measurement Radiometer

UVRead is a high-performance UVA radiometer designed for quantitative measurement of high-intensity UVA, such as the UV spot-light used for industrial epoxy curing. It comprises a sensor module with a set of detachable standard light-guide adaptors for diameters of 3, 5 and 8 mm, and a reader module connecting to the former for the display of the measurement. This allows accurate measurements of the UV intensity of a curing system. The UVRead measures UV intensity measurement up to 12 W/cm2.

Another main benefit of the UVRead is its high durability and its longer calibration validity (2 years). This results in a lower running cost, hence reducing production costs.

Patented Technology

UVRead is developed through the technical collaboration between TechnoDigm and Institute of Materials Research and Engineering (IMRE), Agency for Science, Technology, and Research (A*STAR).

Based on a unique patented IMRE ferroelectric photovoltaic UV sensor technology, UVRead is built for durability and efficiency.

It has gone through numerous rigorous testing and has the ability to withstand continuous intense UV exposure over a long period of time without exhibiting any significant performance degradation.
