Graphite Digester (QTX-GD Series)

The heater is designed separately from the control system to prevent corrosion of electrical components.
Sample soaking → digestion → acid driving is completed with one button, which is convenient, fast and has large sample processing capacity
Graphite heating module is made of high-density graphite, which has the features of uniform temperature distribution, high temperature resistance and low temperature buffer.
With widely range of applications, the temperature and heating rate of furnace hole can be adjusted continuously. With excellent corrosion resistance, the shell is made of 316 stainless steel with teflon coating.
The intelligent temperature control system adopts 5-inch color touch screen, and the information display is detailed, easy to understand and operate
The input method of recipe program is tabular fast input method with clear logic, fast speed and not easy to go wrong.
0-40 sections of program can be arbitrarily selected and set.
Dual-mode of single point heating and curve heating that can be arbitrarily selected.
Intelligent P, I, D self-adjustment with high precision, reliability and stability.
The electrical control system uses solid state relay (regulating module) for mute and strong anti-interference capability.
Segmented power supply and restart function to avoid power failure preventing potential risks
