Thermometry in Engine Research: The Advantages of Thermo‐Electric Type Instruments for Obtaining Temperature Readings Under Difficult Conditions

IN research or development work on aero engines there are many occasions when it is desirable, or sometimes essential, to obtain temperature readings under somewhat difficult conditions. In many cases it is possible for serious errors to arise, under conditions which make their detection difficult, and the writer, therefore, thinks that the information he has gained in dealing with these problems may be of value to others.
