主要功能及特色

I. Core Functions
1. Precision constant-temperature drying:
1.1. Electric heating tubes, high-accuracy temperature sensors and a PID controller maintain set-point within ±0.1 °C and uniformity within ±1 °C over the range ambient +10 °C –200 °C. Suitable for drying, curing and baking of reagents, electronic components, materials pre-treatment, etc.
1.2. A powerful blower and optimized air duct circulate hot air evenly, eliminating local hot/cold spots and guaranteeing consistent drying of every sample in the batch.
2. Intelligent operation & protection:
2.1. Digital panel allows exact setting of temperature and time (0–9999 min). The oven can auto-power-off or remain at set temperature when the timer ends, eliminating the need for constant supervision.
2.2. Multiple safety functions: tracking alarm (+10 °C), over-temperature alarm with heating cut-off, overload protection, cool-touch outer shell; selected models add earth-leakage protection.
3. Sample compatibility & ease of use:
3.1. Two to five height-adjustable shelves (5–10 kg load each) accept various sample sizes and types, from laboratory glassware to small industrial parts.
3.2. Double-layer toughened-glass door with interior lamp lets users check progress without opening the door, avoiding temperature loss and extended drying times.

II. Key Features
1. Energy-efficient & stable:
1.1. High-grade Ni-Cr heating elements combined with a triple-layer chamber (304 stainless-steel liner, high-density mineral-wool insulation, powder-coated steel outer shell) minimize heat loss and power consumption.
1.2. Brand-name thermostats, blower motors and heaters give low failure rates and permit continuous runs of many hours to several days for research or small-scale production.
2. Superior materials & easy cleaning:
2.1. 304 stainless-steel interior resists corrosion and high temperatures, wipes clean in seconds and meets laboratory hygiene standards.
2.2. Electro-statically sprayed exterior is scratch- and chemical-resistant, retaining a new appearance after years of use.
3. Wide applicability:
Ideal for biology, chemistry, electronics, materials science and food laboratories: dehydration of biological samples, solvent removal, moisture-proofing of PCBs, moisture-content sample prep, etc.
4. User-friendly:
4.1. Straightforward panel—no training required.
4.2. Plug-and-play: place on a level surface, connect to mains and start. Quiet blower motor keeps noise below laboratory background levels.

一、核心功能
1、精准恒温干燥功能:
1.1、其一是采用电热管加热方式,配合高精度温度传感器与PID智能控温系统,控温精度可达±0.1℃,温度均匀性±1℃,支持室温+10℃~200℃控温范围,满足不同样品干燥、固化、烘焙需求(如实验室试剂干燥、电子元件固化、材料预处理等)。
1.2、其二是内置强力鼓风装置与风道循环系统,使箱内热气流均匀扩散,避免局部温度偏差,确保批量样品干燥效果一致性,防止出现部分样品干燥不彻底、部分样品过度干燥的情况。
2、智能运行与保护功能:
2.1、其一是配备数字式控制面板,支持温度、时间参数精准设定,定时范围(0-9999min),到达设定时间后自动断电或恒温保温,无需人员全程值守,提升实验效率。
2.2、其二是内置多重安全保护机制:跟踪报警(+10℃),超温报警与断电保护(温度超出设定阈值时自动切断加热电源并报警)、过载保护(避免电路过载损坏设备)、箱体外壳防烫设计,同时部分型号具备漏电保护功能,全方位保障实验安全。
3、样品适配与便捷操作功能:
3.1、其一是箱内配备可调节高度的多层搁板(通常2-5层),支持不同尺寸、不同类型样品的放置,搁板承重能力强(单块承重可达5~10kg),适配实验室常规样品、工业小型部件等多种场景。
3.2、其二是采用双层钢化玻璃观察窗,搭配内置照明装置,可实时观察箱内样品状态,无需打开箱门即可掌握干燥进度,避免频繁开门导致温度波动、延长干燥时间。

二、核心特点
1、高效节能,运行稳定:
1.1、其一是加热管采用高品质镍铬合金材质,发热效率高、使用寿命长,配合保温性能优良的箱体(内层不锈钢+中间高密度保温棉+外层冷轧钢板),减少热量损耗,节能效果显著。
1.2、其二是核心部件(温控器、鼓风电机、加热管)均采用知名品牌配件,设备运行故障率低,连续工作稳定性强,可满足长时间(数小时至数十小时)连续干燥需求,适配科研实验与小规模生产场景。
2、材质优良,清洁便捷:
2.1、内胆采用304不锈钢材质,耐腐蚀、耐高温、不易滋生细菌,且表面光滑无死角,样品残留或污渍可轻松用无尘布擦拭清理,符合实验室洁净要求,避免交叉污染。
2.2、箱体外壳经静电喷塑处理,抗刮擦、防腐蚀,外观整洁美观,且易于日常清洁维护,长期使用仍能保持良好状态。
3、适配性广,场景灵活:
适用领域广泛,可满足生物、化学、电子、材料、食品等多个行业的实验需求,如生物样品脱水干燥、化学试剂提纯、电子元器件防潮处理、食品样品水分测定前处理等。
4、操作简单,门槛低
控制面板设计简洁直观,温度、时间设定一目了然,无需复杂培训,新手即可快速上手操作,降低实验人员学习成本。
无需复杂安装与调试,开箱后放置平稳、接入电源即可使用,且设备运行时噪音低(鼓风电机静音设计),不会对实验室环境造成干扰。
