HCT-1/HCT-2/HCT-3/HCT-4 Microcomputer Differential Thermal Balance(Comprehensive Thermal Analyzer)

It is mainly used to measure physical and chemical changes related to heat, such as studying changes including the melting point, heat of fusion, crystallization and heat of crystallization, heat of phase transition reaction, thermal stability (oxidation induction period), glass transition temperature, adsorption and desorption, content analysis of components, decomposition, combination, dehydration, and additives of substances.

Instrument Feature of HCT-1/HCT-2/HCT-3/HCT-4 Microcomputer Differential Thermal Balance(Comprehensive Thermal Analyzer)

01

1

Heat-flux DSC: Data acquisition method, which plots a curve of energy versus temperature.
02

2

Users can independently calibrate the accuracy of temperature, energy, and thermogravimetry using standard samples.
03

3

The atmosphere control system employs mass flow controllers, enabling switching between three channels of pressure-stabilized and flow-stabilized gases during experiments. It offers high precision, excellent repeatability, and rapid response (custom atmosphere control systems resistant to various corrosive gases are available).
04

4

Accommodates both micro-samples and large-volume samples (maximum sample size up to 5g by replacing the support rod), meeting testing requirements for diverse samples under varying conditions.
05

5

The entire measurement process is fully automated, with automatic plotting. Its comprehensive software supports routine data processing for DTA, TG, DTG, and DDTG, as well as specialized analyses (e.g., DTA peak area calculation, enthalpy determination, kinetic parameter computation, data comparison, activation energy calculation via multiple algorithms, glass transition temperature measurement, and specific heat determination by comparative methods).
06

6

During sample data collection, the system allows screenshot capture at any time and automatically adjusts the measurement range based on output signal intensity.
07

7

Large-screen LCD display, which displays the instrument status and data in real time. It is equipped with two sets of thermocouples: one set displays the sample temperature during operation, and the other set displays the furnace temperature in real time (regardless of whether the heating furnace is working or not).
08

8

Our company can promptly develop customized software based on calculation formulas or methods provided by users.
09

9

Independently developed constant-temperature controllers, constant-temperature connectors for gas chromatography and mass spectrometry, and constant-temperature zones ensure reliable secondary detection of tar and various reaction gases.
