Muffle Furnace With Communication Port 7.5L Overview
The Yamato FO300CR is a 7.5 L muffle furnace with a communication port, built for high-temperature work from 100 to 1150°C: ashing, fusing glass, enamel coatings, ceramics, and soldering and brazing metals. A microprocessor PID controller holds ±2°C at 1150°C, and the firmly sealed chamber door keeps heat in.
The FO300CR is the previous-generation FO model; Yamato's current part number for this size is the FO301CR. It runs on 115V single-phase power (19 A, no plug, round terminal) and stores up to 6 programs. LabSupplies.com is an authorized Yamato Scientific dealer.

Frequently Asked Questions
What is the difference between the Yamato FO300CR and the FO301CR?
The FO300CR is the previous-generation part number and the FO301CR is Yamato's current model in the same 7.5 L size. Yamato's FO brochures list the same 100–1150°C range, ±2°C accuracy and ~37 kg weight for both; the current model uses a Kanthal AF iron-chrome heater.
What power does the FO300CR need?
115V single phase, 50/60 Hz, 19 A. It ships without a plug (round terminal), so plan for hard wiring or a matching receptacle.
What are the chamber and outside dimensions of the FO300CR?
Internal 200 × 250 × 150 mm (W × D × H), 7.5 L. External 446 × 505 × 567 mm (17.6 × 19.9 × 22.3 in). Unit weight is about 37 kg.
Can the FO300CR run temperature programs?
Yes. It stores up to 6 patterns (30 steps × 1, 15 steps × 2, or 10 steps × 3) and also runs fixed-temperature, quick auto stop, auto stop and auto start modes, with a timer from 1 minute to 999 hours.
What safety features does the FO300CR have?
Self-diagnostics for memory error, heater disconnection, sensor error and SSR short circuit, an electric leakage breaker, an overheat prevention device, key lock and power-failure compensation.
What options are available for the FO300CR?
Yamato lists an exhaust system unit, N₂ gas loading device with flow meter, temperature output terminal, time-up/alarm output terminal, and sample tray.
Where is the Yamato FO300CR manufactured?
Yamato Scientific lists China as the country of origin.
