Key Features
- The Automatic microprocessor based TGA is programmed to perform complete and automatic analysis of Air-Dry Basis Moisture, Ash & Volatile Constituent in Coal
- Latest design allows measurement up to 19 samples in every batch in accordance with ASTM D-7582-15 & D-7348
- Additional furnaces can be connected for increased workload to measures 38 or more samples. All the additional furnaces are programmed to be controlled by a single computer
- Both oxidizing and inert atmospheres can be maintained as per ASTM guidelines. Provision shall be made to introduce a sweep gas or a reactant gas, and to remove product of drying, de-volatilization or combustion.
- The sample balance pedestal, crucible and the crucible covers are made of ceramic material as per ASTM guidelines. The crucible and the turn table are capable of withstanding high-temperatures and different furnace atmospheres and is not susceptible to wrapping at high temperature.
- The furnace is programmed to have maximum temperature control up to 1000C with variable temperature ramp rate .The furnace cover of the analyser is supported by two shafts for better stability and support.
- Instrument has two thermocouples which includes one thermocouple for over - temperature protection for safety and the other one to measure and record temperature near the test crucible.
- The versatile and powerful software allows the instrument to store minimum 7 programmes for Moisture, Volatile Matter and Ash determination at temperature programmed by the user depending on the nature of sample.
- Multiple calibration points for Balance & Temperature
- High Precision Temperature Controller ensure Controlled, Precise and Quick Temperature rise
- The system can also calculate the LOI Calorific Value, Fixed Carbon and Hydrogen in the samples based on the values of the parameters obtained
- The instrument is configured with a built-in high Precision Electronic Scale to ensure precise and accurate weighing of the samples
- The software which controls the operation of the TGA has inbuilt programable memory for storage of data and analytical methods along with several other powerful and user-friendly features
- Graphical representation of the analysis & reporting
- Pre calibrated at factory as per the ASTM methods for proximate analysis Auto stop facility is provided
- Latest software features LIMS enabled with Automatic Data Collection, Tabulation and Printing of all test results
- Advanced dust suction and exhaust system fitted to remove the exhaust gases generated during the experiment
