Overview
The Dewar adiabatic storage calorimeter has been widely used in the field of chemical engineering. It can measure the safety of the production, storage, and transportation of various materials such as liquids, solids, slurries, filter residues, and mixtures. The latest calorimeter also adds options for safety design, gas sampling, safety measurement, and low-temperature measurement. Semi automatic data analysis can determine pressure level, temperature level, self heating rate, time to reach maximum value, irreversible temperature, and other parameters.
Product Details
Instrument features:
Large sample size for testing (up to 100mL);High thermal sensitivity (0.1W/kg);Can accurately simulate factories without the need for amplification factors;Good mixing performance, the container can be reused.
Technical parameters:
1. Temperature range: room temperature -300 ℃, temperature control accuracy: ± 0.001 ℃
2. Temperature measurement accuracy: ± 0.005 ℃
3. Temperature rise rate: 0.02 ℃/min -20 ℃/min
4. Heat release test sensitivity (HWS): 0.005 ℃/min
5. It can reliably simulate the "thermal runaway reaction" and describe the worst-case thermal hazard using the adiabatic method in an experiment, providing high-sensitivity data on the entire process time, temperature, and pressure.
6. Operating modes: Heating/Waiting/Searching (HWS), Rapid Scanning (RAMP), Isothermal (ISO)
7. Heat release rate tracking: 0.04 ℃/min -400 ℃/min
8. Calorimetry sensitivity: 0.1 W/kg
9. Pressure range: 0-25 Bar, pressure accuracy 0.01 Bar
10. Sample size: 30ml, 50ml, or 100ml test containers can be selected.
11. For different reaction resolutions and high-quality thermal data, real explosion simulation can be carried out in the calorimeter.
12. Electromagnetic stirring: 0-600RPM
13. Pressure tracking range: Vacuum~200 Bar/min
14. Describe the heat release process under all adiabatic conditions using data. Low phi factor, no need for correction, the results can be represented by scaling up and down curves at different scales.
15. Simulate real working conditions with sensitivity 1 to 2 orders of magnitude better than differential scanning calorimetry (DSC).
