## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: How does an infrared pyrometer measure temperature in metal manufacturing?
**A**: The pyrometer detects infrared radiation emitted by hot metal surfaces through a Germanium lens, converting it to temperature readings without physical contact, ideal for monitoring processes like casting, forging, or heat treatment.

### Q: What is the importance of emissivity setting in metal temperature measurement?
**A**: Emissivity compensates for how different metals emit infrared radiation. Accurate setting ensures precise readings across various metals like steel, aluminum, or copper, which have different emissivity values.

### Q: Why use a purge air connection in metal manufacturing environments?
**A**: Purge air keeps the lens clean from dust, smoke, and fumes common in metal plants, maintaining measurement accuracy and protecting the optical components in harsh industrial conditions.
