Obliczanie niepewności pomiarów z wykorzystaniem interaktywnej bazy danych

The computer calculating of calibration uncertainty make realisation of this task faster and easier. The script language PHP was chosen. This solution gives multiuser support of every operating system with implemented Internet browser and any PC hardware platform. The structure of the program, an example of calibration calculations and results of program's testing are presented in the article. The program is dedicated for students, making laboratory works at University as well as any researchers calculating uncertainty. The address of page is: http://www.ely.pg.gda.pl/niepewnosc.
