Improvement of digital thermometric units for solar collector investigations

The analysis of requirements for metrological parameters of digital temperature meters and temperature difference meters for solar collectors’ investigations been done in the article. Under the regulations requirements a minimum temperature drop not exceed 1,5 K, and for the maximum relative error of temperature measurement not more ±2% it provide the absolute error of temperature drop measurement near ±0,030 K, and their measurement unit list significant digit 0,01 K.
