AET-400 automatic explosion temperature tester

The tester is used for measuring explosion (ignition) temperature of explosive materials and it is equipped with instrumental detection of the explosion point.

Explosion (ignition) temperature is defined as the temperature at which an explosive sample explodes (deflagrates, ignites) when heated with a constant heating rate. The test is described at STANAG 4491.

The tester consists of a temperature controller and a heating block with multiple holes. The temperature of the block is controlled by a temperature controller within 0.1 °C of the desired temperature, using range of heating rates from 0.1 to 20 °C.min^-1 . The measurement of up to 5 samples simultaneously can be carried out at a temperature range from 30 to 400 °C.

The unique feature of AET-400 tester is based on automatic determination of the explosion temperature using thermocouples placed in each sample. The explosion or rapid decomposition of the sample is connected with sharp increase of temperature within the sample due to the exothermal reaction. The explosion temperature can also be determined visually using temperature reading at the digital temperature controller.
