Accelerating Rate Calorimeter 244 (ARC®)

The accelerating rate calorimeter 244 (ARC^® 244) is designed for safe and accurate measurement of the quantity and rate of heat release relating to the processing or storage of chemicals. The instrument was earlier named as TIAX ARC 3000.

The ARC^® 244 technology is fundamental to designing intrinsically safer batteries and measuring energetic materials used in products, including propellants, explosives, and air bags.

Operating modes of the ARC^® 244 are heat-wait-search test for thermal runaway reactions; iso-fixed/iso-track for assessing storage conditions/auto-catalytic reactions; and ramp mode for rapid screening of unfamiliar samples.

Key Features

The main features of the ARC^® 244 are as follows:

High performance

Safety, usability, and flexibility with data

Robustness and integrity in a temperature range from ambient to 500°C

Cost-effective

Tube heater decreases heat losses due to reflux

Windows XP™ operating system standard

Smaller footprint

Lift mechanism for calorimeter top

Experimental wizards to enable easy setting-up of tests

Better safety and interlock features

Over-temperature protection

Tube heater prevents refluxing and sample loss, which can result in significant underestimation of heat reaction and temperature and pressure rates

Automated anneal, temperature calibration and drift tests without the need for operator intervention and with enhanced efficiency

Power compensation module (optional)
