- The preferred choice for chemical safety assessment, effectively preventing the risk of production accidents.
How it works?
The instrument operates in a near-adiabatic environment to track self-heating behavior during controlled heating. During a test, it continuously records sample temperature, pressure, and heat-release related signals, helping users determine exothermic onset behavior and evaluate thermal hazard risks for reactive systems.
The instrument supports multiple test modes:
- Constant-Rate Scanning Mode: screens onset behavior and basic thermal characteristics.
- Isothermal Mode: evaluates stability at a fixed temperature over time.
- HWS (Heat–Wait–Search) Mode: follows self-heating under near-adiabatic conditions and supports thermokinetic analysis.

Q&A
What is the difference between temperature detection threshold and temperature tracking rate?
The detection threshold is the minimum self-heating rate the instrument can recognize as meaningful. The tracking rate is the range at which the system can follow and respond to self-heating during an event.
Why would I choose HWS mode instead of a constant-rate scan?
Constant-rate scanning is typically used for fast screening of onset behavior, while HWS is used to follow self-heating behavior under near-adiabatic conditions and generate data suitable for thermokinetic calculations.
Do I need inert gas cooling after a test?
Inert gas cooling is used to reduce cool-down time and improve operational safety after the experiment, especially when the furnace remains at elevated temperature.
What sample cell options are available?
The standard sample cell volume is 8 mL. Optional sample cell materials include stainless steel, titanium, and Hastelloy, allowing selection based on corrosion resistance and compatibility with the test sample.
What interfaces does the instrument support for data transfer and control?
TAC500AE supports USB or RJ45 interfaces for instrument communication and data handling.
