NULL_INDICATING_DIODE_THERMOMEIER

Microammeter serves as null indicator. When potentiometer is adjusted for zero current, arm of potentiometer indicates temperature value directly. Values of R3 and R4 are chosen to place 25℃ range anywhere from near absolute zero to about 40℃.-L. E. Barton, Measuring Temperature with Diodes and Transistors, Electronics, 35:18, p 38-40.
