PREVENTIVE MAINTENANCE
Maintenance checklist
Each use
- Check gas flow and balance stability
- Inspect the pan and hang-down wire
Monthly / as needed
- Clean the furnace tube and pans
- Check the thermocouple position
Periodic (as per SOP)
- Temperature calibration with Curie point standards
- Mass calibration with certified weights
- Performance check with calcium oxalate monohydrate
Annual
- Preventive maintenance by the service engineer
SAFETY
Safety precautions
Before you work on the TGA
- The furnace may reach 1000 °C or more; let it cool before handling parts.
- Decomposition gases can be toxic; vent the exhaust to an extraction system.
- Secure gas cylinders and check regulators.
- Do not test explosive or highly energetic materials without a risk assessment.
