HCR-1/HCR-2/HCR-3/HCR-4 Differential Thermal Analyzer

It mainly measures physical and chemical changes related to heat, such as changes in a substance's melting point, heat of fusion, crystallization and heat of crystallization, phase transition reaction heat, thermal stability (oxidation induction time), glass transition temperature, etc.

Instrument Feature of HCR-1/HCR-2/HCR-3/HCR-4 Differential Thermal Analyzer

01

1

The smallest integrated instrument in China that combines electromechanics and atmosphere control, reducing signal loss and interference.
02

2

The atmosphere control system adopts a mass flow controller. Two channels of gas with stable pressure and flow can be automatically switched during the experiment, featuring high precision, good repeatability and fast response speed (Atmosphere control systems resistant to various corrosive gases can be customized).
03

3

The entire measurement process is completed automatically with automatic plotting. The software functions can realize DTA conventional data processing and special data processing (including DTA peak area, enthalpy calculation, kinetic parameter calculation, data comparison, activation energy calculation via multiple algorithms, glass transition temperature, specific heat measurement by comparison method, etc.).
04

4

During the sample collection process of the system, screenshots can be taken at any time, and the range can be automatically changed according to the output signal size.
05

5

Users can calibrate the accuracy of the instrument's temperature and energy using standard samples such as indium, tin and lead.
06

6

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).
07

7

Our company can promptly provide corresponding software development products according to the calculation formulas or methods provided by users.
08

8

The independently developed constant temperature controller, constant temperature gas chromatography and mass spectrometry connectors, and constant temperature zones can fully ensure the secondary detection of tar and various reaction gases.
