产品描述
Characteristic：
Photoelectric automatic detection, dot matrix graphic LCD display, touch screen buttons and other technology using WRS 1C and melting point instrument with melting curve automatic recording, initial melting and final melting automatic display function. Temperature control system adopts precision platinum resistance as temperature sensing element,
Application of digital PID control and PWM control technology, to improve the accuracy and reliability of the determination of melting point . The equipment can automatically save the work parameters and the determination results of storage function, can also establish communication through the USB interface or RS232 interface with PC.
The instrument of the Pharmacopoeia as samples by capillary tube.
