High-performance,energy-saving, programmbleconstanttemperature, forced convectionovens with air velocitycontrolandexhaustdampers.高效，节能，程序化恒温控制，送风烘箱配有空气流速控制和废气阀和以前的型号相比，该系列实现节能30％－40％。使用数字设定的控制器，风速可以按照10个挡变换。在主体的前面装上滑动触头式的开关调整旋钮，机器的可操作性被提高了。

Theyachieveanenergy-saving rate of 30 to 40% compared to previousmodels.Airvelocity can be changed in 10 stages using the digitalsettingofthe controller. Operability has been enhanced bylocatingaslider-type open/close adjustment knob on the front sideofthemain unit.

• Special constructionmakesitdifficult for dust from surrounding environment toentertheoven.
• Temperaturesettings,measurementtemperatures, over-heating preventiontemperaturesettings aredisplayed simultaneously with the digitalsetting anddisplaysystem.
• Programmable operationenablesamaximum of 32 steps repeat and graduated operation.
• Calibrationoffsetting,timer,integrated time calculation and other addedfunctions.
• Comprehensivesafetyfeatures.
• A recorder can beequippedasoption.
