Product Introduction

Core Competitive Advantages

1. Dual Test Mode Quick Switch Design
   Two sets of interchangeable specimen fixtures are pre-installed inside the cabinet; operators only adjust burner angle and sample bracket position to rapidly switch horizontal and vertical testing without extra disassembly. Two dedicated burner configurations are matched separately: Model A for 20mm low flame (HB vertical test) and Model B for 40mm high flame (heavy-duty vertical grading), fully covering all UL94 standard flame height requirements.
2. Precise Constant Gas Flow Control System
   High-precision gas flowmeter with ±1% regulation accuracy, fixed standard flow 105ml/min for low flame and 965ml/min for high flame. The burner base adopts motorized front-back alignment structure, jog adjustment to change the distance between flame and specimen, ensuring consistent ignition distance for each parallel test and eliminating manual positioning error. Methane/coal gas dual gas compatibility reduces user gas procurement restrictions.
3. Full Set Intelligent Timing & Printing Control
   7-inch color touch screen paired with PLC core controller, three independent timing channels for ignition duration, residual flame time and afterglow time, adjustable range 0~999.9s with 0.1s resolution. Built-in thermal printer supports one-click output of complete test data curves and grade judgment records, realizing traceable laboratory inspection archives without additional computer connection.
4. Multi-Layer Safety Protection Mechanism
   High-sensitivity gas leakage alarm sensor is installed in the cabinet interior; once fuel gas leakage is detected, the system automatically cuts off gas supply and triggers sound-light warning. The fully enclosed transparent observation door has safety interlock: the burner will stop igniting immediately if the cabinet door is opened during testing. Independent exhaust fan automatically discharges toxic combustion fumes after each cycle to protect lab staff from harmful smoke inhalation.
5. Multi-Angle Adjustable Standard Burner
   The Bunsen burner with standard 9.5mm inner diameter and 100mm effective length supports 20°/45°/90° three angle switching, fully matching all test angle rules of international standards. The flame height can be continuously adjusted from 20mm to 175mm to adapt special high-flame testing schemes for high-strength composite materials.
6. Large Closed Windless Test Chamber
   0.5 cubic meter sealed observation cavity isolates external air flow interference, avoiding flame deflection that distorts burning time data. Large tempered glass observation window provides full visual field for operators to record dripping and self-extinguishing phenomena without opening the cabinet door during testing. The whole machine adopts compact vertical layout, easy to place in standard laboratory countertops.
