The UV-1400 Radiometer + Dosimeter is a self-contained, high quality UV measuring instrument. It is designed to measure, record and display peak UV intensity and UV dosage in the UV curing process. In the standard version it is equipped with one UV sensor for the measuring of:

Full UV spectral area 250 410 nm

Due to its UV sensor and the integrated microprocessor the UV-1400 Radiometer + Dosimeter can measure, record and display the peak UV-intensity of the total UV spectrum (mW/cm2). Additionally, it 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 as the total Integral of UV-dosage over the full UV spectral bands. The UV-1400 Radiometer + Dosimeter features a selectable triggered mode, i.e. the 120 sec recording cycle starts within a 120 second readiness phase not before the incident UV-intensity exceeds 2 mW/cm. The sensor is on the back of the unit which also serves as a heat shield. 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.

While on the conveyer belt, the UV-1400 Radiometer + Dosimeter 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.

CALIBRATION
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
