1200 ℃ Vertical Tube Furnace

1200 ℃ Vertical Tube Furnace
Product Details

CE Standard 1200℃  Vertical Tube Furnace
BR-12NVT vertical tube furnace is a split vertical tube furnace with vacuum sealed 40mm, 60mm, 80mm and 100mm diameter quartz tube, which can achieve faster sample heating and quenching in vacuum or flowing gas. Precision temperature controller can provide 51 segments heating and cooling steps with +/- 1℃ accuracy. It is an ideal furnace for making quenching test and temperature measurement.
