在单晶生长、退火、极化等工艺中,一般要求温度按予定要求自动平滑地升、降或恒温。且变温速度视材料或工艺不同而差别甚大。为此设计该仪器可配合多种控温仪表,适用于各种温控过程。其突出优点是电路简单,故障率极低,造价便宜,具有停电记忆功能,无值班人员情况下使用,安全可靠。仪器电路由三部分组成:时序及推动电路,毫伏设定电路和 In single crystal growth, annealing, polarization and other processes, the general requirements of the temperature required by the automatic smooth rise, drop or constant temperature. And variable temperature depending on the material or process varies widely. Designed for this instrument can be used with a variety of temperature control instruments, suitable for a variety of temperature control process. The outstanding advantages of the circuit is simple, low failure rate, low cost, power failure memory function, without the use of duty personnel, safe and reliable. Instrument consists of three parts: timing and push the circuit, millivolt set circuit and
