TG TGA Thermo Gravimetric Analyzer Thermogravimetric Analyzer
1. Product introduction
1. Furnace is heated with a precious metal rhodium wire double-row winding system to minimize interference.
2. The tray sensor is made of precious metal platinum rhodium alloy, which has the advantages of corrosion resistance.
3. Power supply, the circulation cooling part is separated from the main engine to reduce the influence of heat and vibration on the microthermal balance.
4. The upper open cover structure is is easy to operate. It is very difficult to put samples into the upper part of the furnace, and it is easy to damage the sample bars.
5. The host machine adopts constant temperature water device to isolate the thermal influence of the heating furnace body on the chassis and micro-heat balance.
6. Furnace body can be replaced according to customer requirements
3. Controller and software advantages
1. Using imported 32-bit ARM processor Cortex-M3 kernel, sampling speed, fast processing speed.
2. 24-bit four-way sampling AD collects DSC signal, TG signal and temperature T signal.
3. The power and water circulation parts are independently controlled by an 8bit single-chip microcomputer, so that the main unit and the cooling section are separated from each other without interference, but closely connected, and the cooling section is under the control of the main unit.
4. USB two-way communication is adopted between the software and the instrument to fully realize remote operation. The parameter setting and operation stop of the instrument can be carried out through computer software.
5. 7-inch full-color 24bit touch screen, good man-machine interface.TG calibration can be realized on the touch screen
