Advanced Safety Systems
- Over-Current & Over-Temperature Protection: The furnace automatically shuts off power and triggers an alarm if over-current or over-temperature conditions are detected, protecting both the sample and the equipment.
- Thermocouple Failure Detection: A built-in function detects thermocouple breakage or failure; heating stops and an alarm sounds if an issue is identified, preventing uncontrolled heating.
- Power Failure Restart (KT-12M Pro): The furnace can be configured to automatically resume its heating program once power is restored after an outage, ensuring process continuity.
Operating Principle
KINTEK muffle furnaces operate on the principle of indirect heating. Heating elements located outside a sealed ceramic muffle chamber heat the muffle, which in turn radiates heat uniformly to the contents inside. This design ensures precise temperature control and protects samples from direct exposure to heating elements and potential contaminants from combustion, vital for maintaining material purity and integrity.
