This digital unit automatically determines the melting point of chemical substances. A built-in camera continuously captures real-time images of the samples; digital image processing determines when melting occurs. Intuitive setup menu and front-panel touch screen make operation quick and easy; simply select the start temperature, remp reate, stop temperature, and press start. PID-controlled temperature ramping provides an extremely linear increase in temperature. Audible and visual alarms indicate temperature stabilization, end of melt, and temperature outside of low/high limits that are user selected. Analyze up to three samples simultaneously.
