• ✅【Precision Temperature Control】: Digital PID controller maintains 50-280°C with ±1°C accuracy, indoor temperature from 10-300°C. The digital LCD display clearly shows set temperature, real-time temperature, timer, wind speed, and heating status. Features timer, auto-tuning, over-temperature alarm, and calibration for lab-grade reliability.
• ✅【Uniform Heating Technology】: Dual-channel hot air circulation + high-temp fans, enhances drying efficiency, uniform heat distribution within the chamber. Adjustable fan speed prevents hotspots, ensuring stable performance over time. The synthetic silicone sealing strip ensures excellent airtightness, minimizing heat loss and maintaining consistent internal temperatures.
• ✅【Industrial-Grade Construction】: Stainless steel/galvanized liner (optional) + cold-rolled steel shell. Thickened insulation layer significantly reduces heat dissipation, improving energy efficiency while the reinforced door hinges and double-layer tempered glass window ensure safe using and convenient monitoring.
• ✅【Safety & Efficiency】: Includes overheat protection, reinforced door hinges, and a double-layer tempered glass observation window for safe using and easy monitoring. Optional adjustable trays (support up to 33 lbs each) and ventilation holes for efficient moisture discharge. Low-noise fan design ensures quiet using.
• ✅【Multi-Industry Application】: Laboratory ovens can be used in the following scenarios: ① Industrial manufacturing: electronic coating curing, automotive parts heat treatment, industrial paint; ② Medical research: instrument sterilization, dental mold baking, biological sample preservation; ③ Agricultural processing: grain dehydration, herbal medicine drying; ④ Laboratory: material resistance testing, Chinese medicine extraction; ⑤ Maintenance workshop: metal parts annealing, tool maintenance.
