EQ-GSL-2000X-25 is an ultra-high temperature furnace with 1" I.D x 6" L heating chamber up to 2000 °C under inert gas for materials research. This compac furnace uses a special tungsten heating element design to reach high temperatures at very low power (< 3000 W) . Precision digital controller provides stable temperature control via C Type thermocouple and SCR power supply.
