강화 유리 온도계 - GTT
Glass Toughening Thermometer  
The Land Glass Toughening/Tempering Thermometer - GTT is designed to provide both an accurate measurement at the critical toughening/tempering temperature and a fast response to changing temperatures.

Within the thermometer's measurement range of 300 to 800°C/500 to 1500°F there is a high accuracy span from 625 to 650°C/1150 to 1200°F.
