The thermocouple and platinum resistance thermometry wall chart ''050099DS/A'' provides a wealth of useful, practical data for engineers, scientists, technicians and students concerned with temperature measurement. Published in a convenient A4, 2 sided format, the Chart can be wall mounted or folder housed as required. The Thermocouple side includes cable and connector colour codes, tolerance classes and a shortform table of calibration values. The platinum Resistance Thermometer side includes the new tables of tolerance classes for wirewound and flat film platinum resistors.
