Test Chamber Features
• Made from stainless steel with nice appearance and rust corrosion
resistance
• Ventilation and smoke-releasing system on top for exhaust gas
removal
• Steel glass door on front for observation during testing
• Operate panel on right side of observation door
• Chamber specification: 200X120X200(CM), volume: 4.8m³
Control System Options
Intelligent Touch Screen + PLC: Controls testing time, frequency and extended time with menu-type
operation and accurate results
Time Relay Control: Traditional relay control for testing time (0~999.9S), stop
burning time (0~99.9s), burning frequency (1~9999), and extended
time (0~999.9S)
Extended Control System
High accuracy extended burning control system (photographic control
system) automatically records stopping burning time, reducing
testing tolerances
Temperature Testing System
• Thermal sensor with copper pipe construction and thermocouple
• K-type thermocouple with 0.5mm diameter stainless steel pipe
coating
• Intelligent PID temperature list matched with K-type
thermocouple, indication over 1000℃
Burning Air and Flow Control
Burning Air: Methane (purity 98%, thermal number 998 BTU/cubic feet, 37.1 per
cubic meter mega joule)
Control System Includes: Flow meter and pressure reducing valves
Flow Meter: Calibrated by D3195 criterion with 2% accuracy, flow scale
1000ml/min
Pressure Reducing Valves: 1 EA, air flow shift to 10 pound/cube inch
