Solid Autoignition Temperature Tester
This instrument is designed to determine the relative autoignition temperature of solid substances. The sample is loaded into a 20 mm standard cubic wire-mesh basket and heated at a constant rate in a programmable temperature-controlled oven to precisely observe the critical temperature at which the substance undergoes spontaneous ignition due to self-heating oxidation. Applicable to industrial chemicals, pesticide technical materials, and solid powders, it provides critical technical data for fire hazard classification of chemicals, process safety temperature specifications, and identification of self-ignition characteristics in hazardous waste.
