The B-Tron features automatic liquefaction from any starting water temperature and automatically corrects for absolute temperature control. Separate display panels indicate the temperature of each bath, while function lights indicate liquefying and timing modes. Audible signals inform when materials are liquefied and when they are ready for use in the mouth. The B-Tron is factory programmed with preset temperatures for immediate use. (Temperatures and timers may be easily reprogrammed by operator, if desired.)
