Q&A

Features

Features adiabatic thermal runaway, auxiliary heating with heating wires, gas collection and pressure testing, thermal/electrical/mechanical abuse, specific heat capacity testing, charge/discharge heat generation testing, multi-point temperature measurement, and video surveillance.

The standard low-temperature cooling module can reduce the initial experimental temperature to -25℃.

Self-exothermic detection sensitivity is significantly better than the standard threshold of 0.02℃/min, with high adiabatic performance and minimal wall-sample temperature difference.

An innovative auxiliary heating wire solution can increase experimental efficiency by up to 5 times.

The furnace features a bursting disc and spring lock design, and includes a standard explosion-resistant box. This dual protection ensures the safety of both experimental personnel and equipment.
