ARC—L120
Ultra-large Adiabatic Accelerating Rate Calorimeter
Product Description
The ARC-L120 redefines the boundaries of large-format adiabatic calorimetry. With a cavernous 50 × 44 × 120 cm chamber accommodating cells, modules, and blade batteries from 20 Ah to 800 Ah, it enables full-scale testing at true article size — no extrapolation, no scale-up correction. The upgraded dual-loop independent design with dual electrodes delivers simultaneous dual-test capability in a single platform, producing data that is both representative and reproducible

Overview
20 Ah – 800 Ah cell coverage.
Dual-loop independent architecture. Two independent electrical channels enable parallel testing and differential electrical testing on a single instrument.
Dual-electrode configuration eliminates self-heating artifacts from the electrodes themselves, ensuring accurate results not only on large-format cells but also on smaller formats such as 18650 and 21700
Optical Video Camera for visualising battery thermal runaway
