- Type R and S: High-temperature options, used in specialized industrial applications.
Pricing Factors
- Material quality: High-quality thermocouples typically cost more due to durability and lifespan.
- Type selection: Prices vary between types; for example, Type K may be less expensive than Type R.
- Brand reputation: Established brands often charge a premium for reliability.
Typical Price Range
| Thermocouple Type | Price Range (USD) |
|---|---|
| Type K | $15 – $50 |
| Type J | $10 – $40 |
| Type R | $50 – $150 |
| Type S | $60 – $200 |
- Assess compatibility: Ensure the thermocouple fits your furnace model before purchase.
- Follow manufacturer guidelines: Refer to the installation manual for specific instructions.
- Safety measures: Turn off power and gas supply before beginning installation to prevent hazards.
By understanding thermocouples, you can make informed decisions regarding maintenance, repairs, and costs associated with furnace operation.
