  • Equipped with high temperature quartz glass tank;
  • Equipped with supported and unsupported sample clamps;
  • Equipped with portable ignition device, gas tank connector, accurate pin valve to adjust the flame;
  • Digital setting N2 and O2 concentration;
  • Computer+LABVIEW software to control N2 and O2 mixing ratio, read O2 concentration in mixing chamber, and store&print out test results;
  • Reserve a calibration port to calibrate the sensor;
  • Stainless steel air channel design, equipped with one way fire-resistance valve, magnetic valve, fine filter, so, it is stable and safe;
