HFWK-500 microcomputer intelligent temperature controller

Product Overview

HFWK-500 microcomputer intelligent temperature controllerIt is an intelligent instrument used to control the heating temperature and time of the muffle furnace during coal quality experiments. It can be applied to various types of muffle furnaces and can also be used for temperature and time control of various resistance high-temperature furnaces.

HFWK-500 microcomputer intelligent temperature controllerUsing a microcontroller as the control center and touch keyboard input. Can strictly follow the relevant national standards to automatically complete temperature and time control for slow ash, fast ash, Roga index, volatile matter and other experiments. Widely used in industries such as coal, electricity, metallurgy, petroleum, chemical engineering, and scientific research departments.
