The UV-3C-T Cube Logger is a self-contained, high quality UV measuring instrument. It is designed to measure and display peak UV intensity and UV dosage in the UV curing process. It is equipped with three different UV sensors and one temperature sensor for the individual measuring of

UV-A 315 410 nm
UV-B 280 315 nm
UV-C 230 280 nm
UV-V 395 445 nm*
UV - 230 410 nm
Temp 32 to 230 F / 0 to 110 C

With these three different UV-bands plus the total UV band and an extra temperature measuring, most of the measuring requirements of UV curing applications can be covered. Due to its three different UV sensors and the integrated microprocessor the UV-3C-T can measure, record and display the peak of the UV-energy (mW/cm2) for each UV-band individually plus the peak of total UV energy. Additionally, this UV-Integrator is calculating the UV-dosage (mJ/cm2) of the UV energy supplied during the time of exposure of one measuring cycle. The UV-dosage is calculated for each UV-band (UV-A, UV-B and UV-C or UV-V) individually and as total Integral of UV-dosage over all three UV-bands. This allows to determine not only the total energy, but also how that energy is delivered, i.e., what intensity and dose at what UV-band. An extra sensor measures temperatures from 32 to 230 F / 0 to 110 C
*This Microprocessor Logger features a selectable triggered mode, i.e. the 30 sec recording cycle starts within a 120 second readiness phase not before the incident UV-intensity exceeds 2 mW/cm.

The sensors are on one side of the unit in different directions, while the display is on the opposite side. After completion of the measuring cycle the measuring results can be scrolled through on the built in 2 x 16 digit LCD display. A special AUTO-OFF feature that turns off the unit automatically after one minute serves as energy saving and extension of the battery service life.
The UV-3C-T Cube Logger is optionally available equipped with an SD-Card Slot and an evaluation software for downloading the data to a computer to show, edit and store a history of the measuring results of the entire measuring cycle as graphic charts (mW/cm2) and (mJ cm2)

While on the conveyer belt, the UV-3C-T Cube Logger can withstand max. 230 F / 110 C for up to 10 seconds. The temperature of the housing should not exceed 113 F / 45 C.
Because of uneven radiation distribution of the UV light source and different type of construction of the measuring devices by different manufacturers, different readings may appear under the same measurement conditions.

In order to keep its full function and precision it is recommended to have re-calibration done once per year. Re-calibration will also be necessary after change of battery. PTB traceable calibration acc. to DIN EN ISO / IEC 17025 with certificate
