This paper presents a system for the control and recording of physical parameters inside a chamber for UV-C irradiating of biological material. The system was based on the HOBO U23-002 temperature and humidity recorder equipped with an integrated external probe, BASE-U-4 optical reader for programming and reading data from HOBO U series recorders, LIGHT METER radiation meter UVC-254 model equipped with a photodiode probe (LP UV-C 01) with a sensitivity of 0.19 μW.cm-2 and sampling time 0.4 s, HOBOware Lite software (for archiving temperature and relative humidity measurement results) with a PC, RS-232 serial interface and dedicated software (SWU-801 LUTRON and SW-U101-WIN) enabling interaction with the meter (for archiving UV-C radiation measurements) and a PC. The operation of the system was tested in real operating conditions of the chamber, by irradiating potato tubers of Innovator variety at different settings of the UV-C radiator. The data obtained was analysed against the significance level assumed of α = 0.05. Significant influence of the qualitative predictors on the dependent variables examined was shown.
