This book was released on 1977 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A method using the defined equations of the International Practical Temperature Scale of 1968 (IPTS-68) for calibrating platinum resistance thermometers in the range from -182.962 to +630.74°C is described. Incorporating the specified IPTS-68 procedure, the method also provides for the accommodation of additional data points in both the negative and positive scale regions at any desired temperature level. The PRT68 computer program, also described and illustrated, was written in FORTRAN language for the CDC-6600 computer to implement this method.
