The Yamato FP-413 is the largest FP high-performance muffle furnace at 11.3 L, reaching 1150 °C with ±1.5 °C control accuracy at top temperature — tighter than the standard FO line — driven by a PID microcomputer with jog-dial setting, a Pyromax heating element, and a single-piece vacuum ceramic-fiber furnace casing. Its 16-segment ramp programming and 300 × 250 × 150 mm chamber suit higher-throughput reproducible ashing and controlled heat-treatment on a 220 V single-phase supply.

Application Profile
The FP line is the high-performance muffle furnace tier: where the FO series holds ±2 °C, the FP-413 holds ±1.5 °C at 1150 °C and adds 16-segment ramp programming so multi-stage heat treatments — controlled ramp-up, isothermal soak, and defined cool-down — run reproducibly rather than as a single set-and-hold. At 11.3 L (300 × 250 × 150 mm) with a 3.25 kW Pyromax heater, it is the largest FP, sized for higher-throughput ashing series and larger heat-treatment loads to sensitive heating-rate protocols.
Two design choices set the FP apart: the Pyromax heating element and the single-piece vacuum ceramic-fiber casing, which together give fast, uniform heating with a robust chamber, while the PID microcomputer with jog-dial entry, clock, and total operating-hours counter support documented, auditable operation. As with any muffle furnace, allow complete burn-off before gravimetric weighing, and add the optional exhaust device unit for volatile or corrosive off-gassing; the φ18 mm exhaust opening and optional N₂ gas leading device support controlled-atmosphere work.
Frequently Asked Questions
What accuracy does the FP-413 hold, and how is it better than the FO line? It holds ±1.5 °C at 1150 °C via PID microcomputer control — tighter than the FO series' ±2 °C — and adds 16-segment ramp programming for staged profiles.
How big is the chamber? The internal volume is 11.3 L (300 × 250 × 150 mm) — the largest in the FP line, driven by a 3.25 kW Pyromax heater.
What is the electrical supply? It is a 220 V AC single-phase unit drawing 17.5 A (documented base model FP410).
What heating element and chamber does it use? A Pyromax heater in a single-piece vacuum ceramic-fiber furnace casing.
What ships with it? Instruction manual, warranty, and a thermal fuse. Optional accessories include an exhaust device unit, sample tray, N₂ gas leading device, external alarm, temperature output terminal, and an outer communication adapter.
