System of thermostatic control on Peltier thermopiles and microprocessor control for a portable NMR relaxometer

Liquid equipment for thermostatic control of samples with accuracy better than 0.1 degree C within the temperature range from -20 to +70 degree C is designed for small-sized NMR spectrometers. The difficulty in using this equipment is a thermomodule based on the Peltier effect. The temperature control system is based on a single crystal microcomputer. The equipment fits modern small-sized NMR spectrometers, which facilitates medical and biological studies.
