1700℃ Single Zone Tube Furnace
Sigma 1700 ℃ single zone tubular furnace is a laboratory tubular resistance furnace produced by Luoyang sigma high temperature electric furnace
Introduction
sigma tube furnace uses 1800 type silicon molybdenum rod as heating element, adopts double-layer shell structure and 50-stage program temperature control system, phase shift trigger, thyristor control, furnace with alumina polycrystalline fiber material, double There is an air-cooling system between the furnace shells, which can quickly raise and lower the temperature. The ends of the corundum tubes are sealed with stainless steel flanges. The flow rate is controlled by a flow meter. The furnace has a warm field balance, low surface temperature, fast temperature rise and fall, and energy saving. The advantages are the ideal products for high-temperature atmosphere sintering, atmosphere reduction, CVD experiment and vacuum annealing in universities, research institutes and industrial and mining enterprises.

| Temperature control type
| UAV program temperature control instrument (standard) 1, 30-stage program temperature control intelligent PID adjustment. 2. With over-temperature protection, the electri℃furnace heating circuit is automatically cut off when the temperature is over-temperature or broken, (when the electri℃furnace temperature exceeds 1720 degrees or the thermocouple is blown, the A℃relay on the main circuit will be automatically disconnected, the main circuit is broken. On, the ON light on the panel is off, the OFF light is on, and the limited protection electri℃furnace). 3, with 485 communication interface (standard when purchasing software) 4, with power-off protection function, that is, when the power is turned on after the power is turned off, the program does not start from the starting temperature, but the furnace temperature rises from the time of power failure. 5, the meter has the function of temperature self-tuning
