RESUMO
The paper describes a MPT-110 temperature microcontroller developed by the closed joint-stock company "OPLEKS" (Orel, Russia) and the results of comparative tests performed in the @IIICC-80 drying sterilizing cabinet. The use of the MPT-110 controller is shown to improve the quality of control and to shorten the times that is taken for the cabinet to reach the preset temperature point.

Assessment of means for individual eye protection by the method of visocontrastometry, allows, already at the stage of projecting, to determine the correctness of selecting vision glasses by conditions of visual work. Investigations of 3 kinds of goggles: for reindeer breeders of Far North (2 variants), for mechanics and for protection from pesticides have shown that by their influence on frequency-contrast characteristic all they comply with physiologic hygienic demands. The value of the used method of control of the quality of individual eye protection means is established.

Measurements of spectral translucent coefficients of four types of protective spectacles with clean and tinted glasses were done using the C phi-46 spectrophotometer. Translucent coefficients were calculated according to a special programme in relation to the visibility factor curve. Vision acuity evaluation for the analysed spectacles is given. It was found that the change of vision acuity in relationship to the glass tinting degree does not directly depend on their translucent coefficient change.
