Simple Constant-Temperature Oven and Control System
G. R. Gunther-Mohr, Sol Triebwasser · IBM Journal of Research and Development · 1957
A number of laboratory measurements require a constant and uniform ambient temperature. A thermocouple-monitored system consisting of an oven, a stable reference source and a chopper-amplifier controller unit has been developed. This system provides a stable and uniform temperature, ±0.1°C from 200° to 1050°C in a cylindrical region 5 cm in diameter and 12 cm long. Each of the parts of the system is discussed and their operation as an integrated whole considered.
