The LIT 400™ (Dust Layer Ignition Temperature Tester) is used for determination of minimum temperature of a hot surface leading to thermal degradation or ignition of dust layers of a defined thickness.

APPLICATIONS

Spontaneous ignition of dust layers is a great risk in industries where flammable dust particles can get accumulated. Knowledge of minimum temperature of a hot surface which will lead to dust layer ignition provides important information for risk analysis, safety planning and prevention of fires or explosions in process industries.
 

ADVANTAGES & FEATURES Hot surface working temperature range up to 450 °C Stable temperature conditions ± 2 °C Hotplates designed with a non-corrosive abrasion-resistant surface or aluminum plate Four types of stainless steel rings as sample holders for the dust layers Stainless steel set for easy dosing and cleaning Recording, archiving and data analysis on PC Robust stainless steel case
