Programmable Muffle Furnace
Laboratory box furnace to 1200 °C with programmable PID control, uniform chamber and double over-temperature protection.
- Max 1200 °C, PID program control
- Double over-temperature protection + door switch
- Chamber uniformity suitable for GB/ASTM ashing
- Benchtop footprint, standard and custom chamber sizes
Overview
The RI-MF1200 programmable muffle furnace covers ashing, ignition-loss, fusion and heat-treatment workflows alongside our proximate analyzers. Multi-segment programmable PID control follows national-standard heating curves automatically, and double over-temperature protection plus a door safety switch protect operators.
High-quality chamber insulation keeps exterior temperatures low and temperature uniformity within a few degrees across the working zone, giving consistent ash results from corner to corner.
Key Features
Programmable curves
Store multi-step heating programs matching GB/ASTM ash and volatile methods so every operator runs the same curve.
Safety first
Independent over-temperature cutout, leakage protection and door interlock as standard.
Pairs with analyzers
Ideal backup/manual method equipment next to automatic proximate analyzers in trade and arbitration labs.

Standards: what each number covers
Buyers compare instruments by standard number, then have to look up the title and the relationship. This table does that for you. “Declared” means the method is named for this model; “equivalent” means the method is compatible in principle and must be verified against your own procedure; “referenced” means the standard supplies qualification or test conditions rather than the measurement itself. Final method compatibility depends on the configured instrument and your written test procedure.
| Standard | Title and relevance | Relationship |
|---|---|---|
| GB/T 212-2008 (ashing) | Proximate analysis of coal — ash determination clause (GB/T 212)The ashing clause of the proximate-analysis standard: 815 °C class ashing programme. | Declared compliance |
| ASTM D3174 (equivalent method) | Standard Test Method for Ash in the Analysis Sample of Coal and Coke from CoalListed as an equivalent ashing method for the muffle furnace; confirm the furnace programme and soak time with the procedure. | Equivalent method |

Frequently Asked Questions
What temperature uniformity do I need for ash determination?
The method fixes the ashing temperature and requires that the whole sample zone be held at it within the specified tolerance; hot spots near elements or door edges produce low or high ash results that are not correctable afterwards. Before accepting a furnace, map the chamber at the working temperature with a multi-point thermocouple survey — the set-point accuracy on the controller display is not the same thing as chamber uniformity.
Can a programmable muffle furnace replace a dedicated ashing furnace?
For ashing, ignition loss and general heat treatment at temperatures within its range, yes, provided the program can reproduce the method's ramp, soak and cooling sequence. For procedures that require a specific chamber volume, a controlled atmosphere, or a very fast ramp, a dedicated furnace may still be needed. Confirm the program segments and the over-temperature protection arrangement against your written procedure.
Which standards are declared for the RI-MF1200, and are they equivalent or directly declared?
RI-MF1200 is listed with: GB/T 212-2008 (ashing) (declared compliance); ASTM D3174 (equivalent method) (equivalent method). The standards table below shows what each number covers. Final method compatibility depends on the configured instrument and the customer's written test procedure.
Which samples can the RI-MF1200 be used for?
Listed applications: Ash content (manual method), Ignition loss, Fusion preparation, General lab heat treatment. Send the sample matrix, preparation method and reporting standard so the configuration and the acceptance criteria can be confirmed in writing.
How do I get a quotation and the datasheet for the RI-MF1200?
Send the sample type, daily throughput, required standard, destination country, voltage and plug standard, and any prequalification documents your buyer requires. RoyIntelli will confirm the configuration, the documents available for that model and the commercial terms in a written quotation. Final specifications, lead time, warranty and payment terms are confirmed in the Proforma Invoice.
