My work often involves heat treating small batches of steel for custom knife making. I needed a furnace that could accurately reach and maintain specific temperatures for hardening and tempering. The programmable controller and compact size of the Thermo Fisher Scientific furnace caught my eye.
Upon unboxing, the furnace felt solid and well-constructed. The double-shell construction gave me confidence in its insulation capabilities, and the overall design was clean and functional. The immediate competitor was a similar model from Carbolite Gero, but the Thermo Fisher Scientific unit’s programmable controller and UL listing swayed my decision.
My first impression was cautiously optimistic. The furnace seemed like a serious piece of equipment, not a flimsy hobbyist tool. I was eager to see if it could deliver on its promises of precise and reliable heating.
Real-World Testing: Putting Thermo Fisher Scientific Lindberg/Blue M Box Furnaces, 1100 C, Thermo Fisher Scientific Scientific BF51894C Furnaces With Programmable Controller to the Test
First Use Experience
I set up the Thermo Fisher Scientific furnace in my workshop and prepared a batch of O1 tool steel blades for hardening. The initial firing was straightforward; programming the controller was intuitive, though I consulted the manual to understand all the features. The furnace reached its target temperature of 843°C (1550°F) relatively quickly and held it steady, even with fluctuations in ambient temperature.
I tested the furnace in both dry and humid conditions. The external shell remained relatively cool to the touch, thanks to the double-shell design, even when the internal temperature was at its maximum. There was a slight metallic smell during the initial burn-in, but it dissipated quickly.
The furnace was surprisingly easy to use, even with the programmable controller. After a few test runs, I felt confident in setting custom heating profiles for different steel alloys. The safety door switch, which disconnects the heating element when opened, was a welcome feature.
The first time I opened the door at peak temperature, I experienced a significant heat rush. While expected, it reinforced the importance of proper safety gear and ventilation. This highlighted the need for careful planning of the work area.
Extended Use & Reliability
After several months of regular use, the Thermo Fisher Scientific furnace has proven to be a reliable workhorse. The heating elements have shown no signs of degradation, and the temperature control remains consistent. The ceramic fiber insulation still looks like new, showing no sign of cracking or crumbling.
The exterior has held up well, with no signs of rust or discoloration. I’ve found that wiping down the exterior with a damp cloth after each use keeps it clean and presentable. Regular cleaning of the chamber with a soft brush removes any scale or debris.
Compared to my previous Paragon kiln, the Thermo Fisher Scientific furnace is significantly more precise and energy-efficient. The programmable controller allows for much finer control over the heating process, resulting in more consistent and predictable results. This translates to less wasted material and higher quality finished products.
