ABSTRACT
We have developed a monitoring and control system for temperature of water bath in which required a temperature of 293.150 K +/- 5 mK, this uncertainty is necesary so that it can work like national patron. Inside of this bath will introduced the masters capilaries viscosimeters that will use like reference for the calibration of the viscosimeters that will arrived to National Center of Metrology. The control of temperature is made by electrical resistor of 1500 W. This resistor’s heat is made electrically by using the wide of pulse technique (PWM).REFERENCES
