High-performance,energy-saving, programmbleconstanttemperature, forced convectionovens with air velocitycontrolandexhaustdampers.高效，節能，程序化恒溫控制，送風烘箱配有空氣流速控制和廢氣閥和以前的型號相比，該系列實現節能30％－40％。使用數字設定的控制器，風速可以按照10個擋變換。在主體的前面裝上滑動觸頭式的開關調整旋鈕，機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.
