ZR-MITL/MITL type dust layer minimum ignition temperature tester

ZR-MITL/MITL-450A Minimum Ignition Temperature Tester for Dust Layer

The minimum ignition temperature tester for dust layer is used to test the minimum temperature of the hot surface when dust of a specified thickness accumulates on the hot surface and ignites. The MITL-450A dust layer minimum ignition temperature tester is mainly used for evaluating the explosiveness of dust in production and processing sites such as aluminum powder, zinc powder, plastic powder, intermediates of organic synthetic drugs, wheat flour, sugar, sawdust, dyes, bakelite ash, milk powder, tea powder, tobacco powder, coal dust, plant fiber dust, etc., and determining the minimum ignition temperature under dust accumulation state.

ZR-MITL/MITL-450A Minimum Ignition Temperature Tester for Dust LayerTest items

The core testing item is the minimum ignition temperature of the dust layer (MITL). This temperature refers to the minimum hot surface temperature at which a specified thickness of dust layer ignites (such as smoldering or flame burning) on a hot surface under certain experimental conditions. It is one of the key parameters for evaluating the fire risk of dust accumulation status.
