Authentic User Feedback

🔬 Laboratory User Reviews

⭐⭐⭐⭐⭐ Dr. Elena Rodriguez - Materials Science Research Lab
"We've been using the Luoyang Changri 1200°C model for six months now in our ceramic sintering experiments, and it has exceeded expectations. The PID auto temperature control delivers remarkable stability—±1°C accuracy makes a noticeable difference in sample consistency. The inert gas atmosphere with nitrogen flow prevents oxidation perfectly. Setup was intuitive, and the digital panel simplifies programming multi-stage heating cycles."

Purchase Date: February 2025 | Usage Period: 6 months

⭐⭐⭐⭐⭐ Professor James Lin - University Thermal Analysis Lab
"After upgrading from a standard muffle furnace, the Luoyang Changri Pro Model (1400°C) has transformed our high-temperature research. We’re running metallurgical tests up to 1350°C under argon atmosphere, and the triple-layer ceramic insulation maintains heat efficiently—energy use is noticeably lower. The customization option to integrate an O₂ sensor was seamless. Over-temperature protection gives us peace of mind during long overnight runs."

Purchase Date: November 2024 | Usage Period: 8 months

⭐⭐⭐⭐☆ Dr. Amina Patel - Pharmaceutical Development Lab
"Our team uses the 1000°C Base Model for drying heat-sensitive compounds, and the inert gas environment ensures no degradation. We added a humidity sensor through their customization service, which has been invaluable for monitoring drying kinetics. The stainless steel chamber is easy to clean and shows zero signs of corrosion. Only reason for four stars is the slightly longer lead time for the custom configuration."

Purchase Date: April 2024 | Usage Period: 5 months

⭐⭐⭐⭐⭐ Research Technician Mark Zhao - Semiconductor R&D Facility
"This furnace is rock-solid. We run vacuum + nitrogen cycles daily for thin-film annealing, and the gas-tight seals maintain integrity without fail. The heating rate of 40°C/min on the Pro model saves hours across our workflow. Maintenance is minimal—just a quick brush of the ventilation holes monthly. After comparing several brands, this one offers the best balance of precision, durability, and support."
