SDTGA6000 Thermogravimetric Analyzer (Proximate Analyzer)

Application:

SDTGA6000 can be used to determine the moisture, ash and volatile matter as well as calculation of fixed carbon and calorific value in coal, coke, calcined petrol coke and other solid biomass fuel.

Dual Furnaces,stable performance, accurate test result.
19 samples+1 blank sample for moisture & ash; 25 samples+1 blank sample for volatile matter

Product description

Highlights:

①Dual furnaces structure, the system consists of two parts, one for moisture and ash analysis, other for volatile matter analysis.
②For moisture and ash analysis, 19 samples can be loaded once + 1 blank sample position;
③For volatile matter analysis, vertical furnace structure is adopted with 26 positions. Upper part for high temperature volatile matter test while lower part for low temperature cooling and weighing, makes the test result more accurate and test efficiency greatly improved.
④Flexible software design, test procedure, analysis time, temperature etc. can be customized;
⑤Unique sample weighing mode, single sample weighing and batch sample weighing are both available, makes the operation convenient.
⑥After finishing the moisture and ash test, furnace cover will be opened automatically for furnace cooling down, thus to shorten the waiting time for next batch of test, makes the operation safe and efficient;
⑦LED displays on both furnaces to show real-time balance weight data, it makes the sample weighing more convenient.
⑧Automatic temperature calibration function is available.

⑨Unique design to ensure the stability of heating element.

⑩High Stability and Reliability.

⑪Patented technology of heat-resistant to ensure stability and reliability.

⑫Built-in balance ensures unbeatable accuracy, comply with thermogravimetric method.

⑬Using blank crucible to calibrate the influence of the thermal buoyancy.
