HR-4A microcomputer ash melting point tester

HR-4A microcomputer ash melting point tester

Product Overview:

The HR-4A microcomputer ash melting point tester uses a microcomputer to automatically control the ash melting point measurement process. The camera captures the gray cone image and displays it on the designated position of the computer monitor through image processing technology. The temperature change of the furnace is PID regulated and controlled by a front-end single-chip microcomputer, and the temperature is transmitted to the microcomputer system through a serial port, displaying a time temperature image.

Main features:

The microcomputer automatically controls the temperature rise, and the temperature rise characteristics comply with the national standard GB/T219-2008;

The gray cone image is displayed in the image acquisition area of the microcomputer monitor;

The system has the function of storing and calling test results;

■ Optional printing of ash melting point images and temperature values;

Automatically store and display the entire experimental process, displaying the temperature rise time curve; The furnace body can rotate freely, making it easy to take out and layout.

The system runs on Windows XP and above operating systems.

Automatic judgment function: deformation temperature (DT), softening temperature (ST), hemisphere temperature (HT), flow temperature (FT).
