The Yamato FP-103 is a 1.5 L high-performance muffle furnace 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 green-LED readout target reproducible ashing and controlled heat-treatment in a compact bench footprint. This is the 115V variant.

Application Profile
The FP line is the high-performance muffle furnace tier: where the FO series holds ±2 °C, the FP-103 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. That control matters for ashing methods sensitive to heating rate, for material annealing and sintering studies, and for any protocol that must be repeated identically across runs and operators.
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 — for volatile or corrosive off-gassing — add the optional exhaust device unit; the φ18 mm exhaust opening and optional N₂ gas leading device support controlled-atmosphere or vented work.
Frequently Asked Questions
What accuracy does the FP-103 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.
What is the maximum temperature? The operating range is 100 to 1150 °C; time to reach 1150 °C is approximately 80 minutes.
What heating element and chamber does it use? A Pyromax heater in a single-piece vacuum ceramic-fiber furnace casing.
Can it document run history? Yes — it includes a clock and a total operating-hours counter (to 49999 h), plus calibration offset and key-lock, supporting auditable operation.
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.

Yamato FP high-performance muffle furnace, 1.5 L:
- FP-103 (this product) — 1.5 L, 115V, ±1.5 °C, 16-segment ramp programming
- Step up to FP-303/FP-313 (7.5 L) or FP-413 (11.3 L) for larger charges.
- Choose the FO series instead when ±2 °C accuracy suffices and budget is the priority.
