DTA 551-EX Differential Thermal Analysis

The differential thermal analysis (analyzer) DTA analyzer was developed specifically for evaluation of thermal stability, purity, compatibility and decomposition parameters of energetic materials…

which explosion may cause damage to standard commercial analyzers. Its main features are robust design resistant against explosion of up to several hundred milligrams of explosives (allowing analysis of truly representative samples), high sensitivity due to direct contact of a thermocouple with a sample, high precision and accuracy, large variety of accessories, user-friendly software for data acquisition, analysis and archiving, many testing modes, very low costs of investment and operation. The apparatus complies with requirements of STANAG 4515. These features brought popularity of DTA 551 Ex at dozens of explosives laboratories of many countries; some of them operating the instrument for more than 10 years.


DTA as a method is applied for evaluation of thermal stability of explosive materials, their purity (melting point, solidification point), compatibility, thermal decomposition parameters. It is used in quality control of manufactured explosives, characterization and qualification of new explosives, surveillance of in-service explosives, R&D and many other testing programs.

Based on proven design of DTA 551 Ex, several other customer–defined instruments are manufactured, e.g. large-scale DTA for sample weights of several grams with simultaneous temperature–pressure measurement in high pressure cells.
