Product Description
The FP series is the answer to a specific complaint about ordinary muffle furnaces: ±2 °C is fine for burning off organics, but it is not fine for ceramics research, thermal analysis, catalyst preparation or any method where the result depends on the exact temperature the sample actually saw. The FP-103 holds ±1.0 °C at 1150 °C, with temperature fluctuation of ±1.0 °C and distribution accuracy of ±4.0 °C across the chamber. Those three numbers, published separately, are what separates a high-performance furnace from a general-purpose one.
Two design choices produce that result. The 1.5 L chamber is lined with alumina fiber rather than ordinary ceramic fiber — cleaner, more refractory, and less prone to shedding particulate onto the sample. And the heater is driven by a triac with zero-cross control instead of a relay: power is modulated smoothly rather than switched in blocks, which flattens the temperature ripple and dramatically extends heater life. The controller stores up to 99 patterns of 99 steps each with repeat operation, so even an elaborate multi-day firing or calcination schedule is programmed once. It also logs cumulative operating hours to 65,535 h and displays power consumption and CO₂ emissions — useful when a facility has to report energy use per instrument.
Key Features
- ±1.0 °C control accuracy at 1150 °C — fluctuation ±1.0 °C, distribution accuracy ±4.0 °C, temperature gradient 14 °C
- 100 °C to 1150 °C operating range
- 1.5 L alumina-fiber chamber — higher purity and better refractory performance than standard ceramic fiber
- R-thermocouple sensor (platinum–rhodium) rated for continuous service at these temperatures
- Triac heater control with zero-cross switching — smoother power delivery, longer heater life, less electrical noise on the supply
- 99 programs × 99 steps with repeat operation
- Dual LED display — orange 5-digit set value, green 4-digit measured temperature, 1 °C resolution
- Operating-hour accumulation to 65,535 h, plus calendar and 24-hour clock for scheduled starts
- Power consumption and CO₂ emission display with heater duty indication
- User setting storage and recall — save an instrument configuration per method or per operator
- Selectable power-failure recovery — decide in advance whether a run resumes or aborts
- Heat-resistant exterior paint and firmly sealed chamber door
- Calibration offset against your own reference thermocouple

- Electric leakage breaker integrated in the unit
- Key lock against accidental set-point changes during a run
What's Included
- FP-103 high-performance muffle furnace
- Exhaust port cap
- Furnace floor plate
- Spare fuse
- Instruction manual
Crucibles and tongs are ordered separately — crucible material depends on your method.
Installation Requirements
- Electrical: AC 115 V, 10 A, 50/60 Hz, supplied with plug. Requires a dedicated 115 V circuit rated above the draw — do not share with other equipment.
- Ventilation: vent the top exhaust port to a fume hood or exhaust duct when ashing organics or anything releasing smoke or vapour.
- Clearance: keep clear of combustible surfaces and leave free space around the cabinet.
- Surface: a bench or stand rated for approximately 64 lb.
