HQC-3 automatic differential thermal analyzer

Characteristics of the instrument

1 furnace automatic control, accurate positioning, improve the measurement repeatability.

2 the atmosphere control system using mass flow controller, pressure, gas can transform two steady flow in the experimental process, high precision, good repeatability, fast response (can be customized control resistance to various corrosive gas atmosphere system).

3 the whole measuring process completed automatically, automatic drawing, the use of software, the functions of conventional DTA data processing; special data processing (DTA peak area, the enthalpy calculation, calculation of kinetic parameters, data comparison, a variety of algorithms to calculate the activation energy, the glass transition temperature, the comparative method measuring specific heat).

4 system to collect the sample process, may at any time according to the screenshots, automatic transform the size of the output signal range.

5 the user can make use of indium, tin with accuracy, lead standard sample temperature, the energy of the instrument calibration.

6. Large screen LCD, real-time display of the instrument condition and data, two sets of temperature measuring thermocouple, a set of galvanic real-time display temperature (regardless of the heating furnace work or not) another set of galvanic couple sample temperature display work.

7. The user gives a calculation formula and calculation method, our factory can provide the corresponding software development products.

8. Independent research and development of constant temperature controller; Constant temperature gas chromatography and mass spectrometry connected head; Constant temperature; Can fully guarantee the tar and various kinds of secondary reaction gas detection.
