The Fire Retardant Coating Tester (Large Plate Method) is designed to evaluate the fire resistance of decorative coatings in laboratory conditions, following national standards. The instrument measures combustion mass loss and chemical volume to assess the effectiveness of fire-retardant coatings. It features high automation, precise temperature control, and touchscreen operation for reliable and user-friendly testing.
The flame-retardant coating tester (large panel method) is widely used for determining the flame resistance characteristics and burning time of fire-retardant coatings. These devices comply with the GB12441-2005 standard, ensuring the accuracy and reliability of the test results. The main parameters of the tester include power requirements, temperature uniformity, sample size, temperature control system, thermocouples, timer accuracy, and automatic alarm, all of which ensure the stability and safety of the testing process.

Turn on the power and access the main control interface of the device's touchscreen.
Click "Start" to begin the test, and simultaneously open the flow meter counterclockwise, adjusting the gas flow rate to approximately 15 L/min.
The system automatically controls the test according to the standard temperature rise curve. After 5 minutes of testing, the gas flow rate increases to its maximum value.
Once the backfire temperature reaches the set temperature, the test automatically stops and a prompt screen appears.
The Fire Retardant Coating Tester (Large Plate Method) provides precise, automated evaluation of coating fire resistance. Its compliance with GB12441 standards ensures reliable and repeatable results for laboratory testing and quality control.
