ARC—D20
Medium-size Adiabatic Accelerating Rate Calorimeter
Product Description
To fill the testing gap between the standard D9 and the high-capacity H60, TSTech has developed the ARC-D20, designed for two-wheel electric vehicles, portable energy storage devices, residential small-scale energy storage systems, and mid-range consumer power batteries. Rugged and durable, the instrument is housed in a safety explosion-proof enclosure (sample capacity: 100 mAh – 20 Ah).
Dual-system design — The D20 shares its explosion-proof enclosure with the D9 calorimeter, allowing seamless switching between material-level testing and medium-capacity cell testing, while a more flexible furnace layout enables integration of additional optional modules
Battery & chemical applications — One system covers cell-level thermal runaway and reactive chemical hazard testing across liquids, powders and pastes.
Dynamic HWS calibration — Real-time offset correction during heat-wait-search delivers near-perfect adiabatic tracking with zero temperature overshoot.
