HR-3A ash melting point tester

Product Overview:

The HR-3A ash melting point tester is manually controlled using the ash melting point measurement process. The gray cone image is collected with the naked eye, and the designated position of the cone image is animated by hand. The furnace temperature change is controlled by PID adjustment using a front-end single-chip microcomputer.

Main features:

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

Manually store and draw the entire experimental process, the furnace body can rotate freely, making it easy to take out and layout.

■ Manual judgment: deformation temperature (DT), softening temperature (ST), hemisphere temperature (HT), flow temperature (FT).
