Fire Extinguisher Test Equipment
Brief Introduction
ZONSKY Standard Fire Extinguishing Test for Class A Fires apparatus is designed to evaluate the effectiveness of fire extinguishing agents on Class A fires, which involve combustible materials such as wood, paper, and textiles. This equipment assesses extinguishing performance by measuring factors such as discharge rate, coverage area, and suppression time.
