Furnace temperature monitoring system with USB transducers was developed. The data were acquired automatically, transferred to PC, and analyzed. Temperatures of five points were measured simultaneously by the system. From the monitored temperatures, temperature distribution was drawn. When the set temperature is 500℃, the difference between set and real temperature is -45～+35℃. When the set temperature is 700℃, the difference between set and real temperature is -11.8～ +35.9℃. In the process of fine ceramics preparation such as high-TC superconductors, the difference between the set and real temperature should be controlled within ±5℃. The optimum area in the furnace was confirmed.
