GB/T 2406.2: Determination of combustion behaviour by oxygen index method -- Part 2: Room temperature test

• Integrated structure, industrial design appearance, beautiful and generous, easy to operate

  
  

• Equipped with two mass flow controllers (MFC), control nitrogen, oxygen mixture ratio, accurate and convenient control

  
  

• Automatic control of closed epoxy concentration, precise control of oxygen concentration in the combustion cylinder

  
  

• Patented gas mixing chamber can ensure that the gas is fully mixed in a short time and the data is more accurate

  
  

• Equipped with gas diffusion ring, mixing glass beads, so that the outlet gas more uniform

  
  

• Equipped with high temperature resistant quartz glass barrel, independent design of the end cover for glass barrel cleaning

  
  

• Equipped with stainless steel supporting and unsupported sample fixture, easy to switch

  
  

• Portable igniter, precision needle valve to adjust flame size

  
  

• Equipped with paramagnetic oxygen concentration sensor, the accuracy of oxygen concentration is ±0.1%, compared with traditional electrochemical oxygen sensor, no service life limit (electrochemical oxygen sensor requires frequent replacement of oxygen cells), higher accuracy, faster response time

  
  

• Imported ring belt heater can preheat mixed gas efficiently

  
  

• Temperature control range of mixed gas: Ambient temperature ~400 ° C

  
  

• The temperature column can be used to observe the sample and also to emit high temperature radiation

  
  

• Equipped with imported K-type armored thermocouple for temperature detection, PID automatic temperature adjustment, set temperature can be stable within ±2℃.

  
  

• Programmable controller (PLC)+ touch screen control, digital setting of nitrogen and oxygen concentration, without repeated manual adjustment, and can set the temperature and feedback.

  
  

• Desktop computer + professional control software to realize the guidance of the whole test process, and store and output test results (optional)
