DTU-3 series high vacuum comprehensive thermal analysis system
Introduction DTU-3 series high vacuum comprehensive thermal analysis system is a high vacuum comprehensive thermal analysis product with independent intellectual property rights manufactured by the company according to the differential thermal and thermogravimetric analysis test standards formulated by the International Thermal Analysis Association. DTU-3 series high vacuum comprehensive thermal analysis system can simultaneously measure the weight change, heat difference and weight change speed of the experimental material in the high vacuum test environment and other professional thermal field information. In addition to all technical tests of simultaneous thermal analysis, test results in diverse atmospheres can be obtained. The precise atmosphere control system unit of the high vacuum comprehensive thermal analysis system provides a high vacuum of up to 2x10-2Pa, which greatly improves professional testing conditions. , especially suitable for petrochemical, metallurgy and other professional fields that require diversity and antioxidant research. Features: 1. Mechatronics design, reliable structure of the whole machine and high signal transmission stability. 2. The vacuum degree of the matching vacuum unit can reach 2x10-2Pa, and the reaction atmosphere of the sample chamber can be switched to the known calibration atmosphere under the vacuum environment, so as to meet the requirements of testing diversity. 3. It can realize cyclic step control temperature program (heating, cooling, constant temperature, step heating) 4. The fourth-generation modular digital circuit design effectively improves the accuracy of sensing signals such as differential heat, thermogravimetric, and temperature control. 5. Differential heat and thermogravimetric signals are collected in a range-free manner, and the circuit and workstation software realize synchronous conversion during the collection process 6. The standard dual-channel voltage stabilization and steady-flow atmosphere control system provides dual-channel scavenging to protect the instrument from corrosive gas pollution. Optional atmosphere 7. The conversion control component can change the type of purge gas during the experiment, and provide a variety of purge gases to meet a variety of experimental conditions. 8. The intelligent software realizes the automatic control of the hardware, completely changing the tedious processes such as manual zero adjustment, setting differential heat, thermogravimetric measurement range gear, and heating switch control of traditional thermal analysis instruments before the experiment. There is no human error, and the stability of the instrument is improved. 9. Users can use the workstation software to calibrate the instrument by themselves, maintain the accuracy of the instrument, and reduce the cost of laboratory maintenance.
