rightMORE INFORMATION

  • TG-DTA/HUM is an instrument where TG-DTA measurements can be performed in a water vapor atmosphere with a constant relative humidity. In TG-DTA/HUM, TG-DTA measurements are carried out under a constant water vapor partial pressure. This instrument can provide a complete understanding of the sample’s thermal behavior with regards to different water vapor partial pressure, effective for applications such as hydrolysis of polymers, thermal behavior of hydrates in pharmaceuticals, debinding of ceramics.
     
    TG-DTA measurements held at a constant temperature while changing the relative humidity measures the absorption ratio with regards to relative humidity useful for the sample’s water absorption property evaluation.
     
    The humidity generator (HUM-1) uses N₂ base gas to create a water vapor containing a humidity controlled gas to be introduced to the TG-DTA.
     
    Here, the TG-DTA is equipped with a specialized electric furnace that keeps the temperature constant through a circulator to prevent condensation even at high water vapor concentration atmosphere and can perform measurements at a maximum of 85℃ 90% RH atmosphere.
     
    The humidity sensor equipped with a feedback control leads to a stable humidity for longer measurements. Since the relative humidity settings in TG-DTA is integrated in the temperature program, the user can change the relative humidity in each step of the temperature program.

    Software:
    1. Measurement data protection function
    During measurement, when a connection error occurs between the station and the module, the module will continue to perform the on-going measurement and the data will be stored in the module. The stored data is retrieved using a PC after the measurement, protecting valuable measurement data.
     
    2. End operation settings function
    The ECO mode or power OFF can be selected after the end of measurement. The temperature and time condition can be specified.
    We can select a variety of operation condition of the attached forced air-cooling fan such as cool up to room temperature, not in use on continuous usage.
     
    3. ECO mode
    After completing measurement, the ECO mode can be selected in the stand-by condition reducing the electricity consumption.
    Especially in TG-DTA, the ECO mode facilitates immediate transition from stand-by to stable measurement conditions.
     
    4. First aid function
    When an error or problem occurs in the module, the error number, error description as well as troubleshooting measures will be displayed facilitating a quick and smooth recovery condition. Also the error contents are stored in log files and can be readily sent to the technical service department for an immediate appropriate response.
     
    5. ASCII data import function
    Using the conversion software, the Thermo plus EVO2 analysis software can analyze carious ASCII converted measurement data.
     
    6. E-mail function
    The Thermo plus EVO2 can transmit information by email such as end of measurement, measurement data, occurrence of an error to PC, mobile phones thru corporate LAN connection abs can confirm the condition of an on-going measurement at remote locations.
     
    7. Excel, Word output
    From the menu directly, the measurement file can be directly exported in Word or Excel. Also, the output style can be modified thru the layoutediting function. When exporting data in Excel, the numerical data will be automatically created in the worksheet 2 allowing a convenient data analysis in other application software.
     
    8. Instrument usage history listing function
    This function automatically records the module’s usage. Information such as date of usage, module name, operator, temperature program and measurement results are filed and saved in the achieve list. The history use of the module and the time of use are clear and effective for management and maintenance.
