High-Precision Laboratory Muffle Furnace 1200°C (TI-MF Series)
High-Temperature Muffle Furnace 1200°C
The Tempo Instruments High-Temperature Muffle Furnace 1200°C is an essential benchtop furnace engineered for loss-on-ignition (LOI) analysis, gravimetric ash testing, heat treatment, metallurgy sintering, glass annealing, and ceramic firing. Built with low-thermal-mass vacuum-formed ceramic fiber insulation and long-life Kanthal A1 heating elements driven by a 32-segment programmable PID temperature controller.
Validation Packages & Accessories
Add mandatory thermal calibration documentation, gas purges, and exhaust accessories for lab audits.
Multi-Point Thermal Mapping & NABL Cert
Full 9-point thermal calibration binder with NABL traceable master platinum sensor report.
Inert Gas Flowmeter & Purge Inlet Port
Rotameter controlled gas purge inlet (Nitrogen/Argon) with gas solenoid safety valve.
Motorized Exhaust Vent Chimney
Automated top-mounted chimney valve to exhaust binder burn-off fumes during ramp cycles.
High-Precision Laboratory Thermal Processing
TEMPO Instruments High-Temperature Laboratory Furnaces are engineered for rigorous analytical applications including loss-on-ignition (LOI), gravimetric ash determination, metal alloy heat treatment, powder metallurgy sintering, and high-temp material synthesis in compliance with ASTM D3174, ISO 1171, and DIN 51719 standards.
Testing Standards Matrix
Industry Applications
- • Mining & Geological: Gravimetric ore assaying & LOI sample preparation
- • Polymer & Chemical: High temperature ash content & filler percentage analysis
- • Metallurgy & Tooling: Hardening, stress-relieving, and tempering of alloy steels
- • Advanced Ceramics: High density sintering of zirconia, alumina, and electro-ceramics
Double-Walled Outer Casing & Heating Architecture
Constructed with a heavy-gauge double-walled sheet steel housing integrated with a forced air cooling jacket, ensuring outer skin temperature remains safe during extended ultra-high temperature soaking. Heating elements (Kanthal A1 / Silicon Carbide / MoSi2) are positioned on all sides for maximum thermal field symmetry.

Frequently Asked Questions & Safety Compliance
TEMPO high-temperature furnaces feature a forced-air cooling air gap between the inner heating core and outer powder-coated steel casing. Even during 1200°C continuous operation, outer casing temperature is maintained under 45°C to prevent accidental contact burns.
Yes, TEMPO Tube Furnaces (TI-TF Series) feature stainless steel vacuum sealing end-flanges with silicon O-rings, gas needle valves, and pressure vacuum gauges for operation up to 10⁻² Torr vacuum or under positive Argon/Nitrogen gas flow.
