FAQ

1. What is the material or composition of an S Type Thermocouple?

An S Type Thermocouple is made of Platinum-10% Rhodium (Pt-10%Rh) as the positive conductor and pure Platinum (Pt) as the negative conductor. This combination provides excellent stability, high precision, and resistance to oxidation, making it suitable for high-temperature applications.

2. What is the temperature range of an S Type Thermocouple?

S Type Thermocouples operate reliably from 0°C to 1600°C (32°F to 2912°F). They are commonly used in laboratory furnaces, kilns, glass melting, and other high-temperature processes where precise measurement is critical.

3. How accurate is an S Type Thermocouple?

S Type Thermocouples are highly accurate, typically rated at ±1.5°C or ±0.25% of the measured temperature. This accuracy ensures stable and repeatable readings in critical high-temperature environments.

4. What is the color code of an S Type Thermocouple?

According to international thermocouple standards (IEC 60584):

Positive wire (Pt-10%Rh): Red
Negative wire (Pt): White
Correct identification of wires is important for proper installation and accurate measurement.

5. How much does an S Type Thermocouple cost?

The price depends on length, insulation type, sheath material, and customization. Standard S Type Thermocouples typically range from $50 to $200 per piece, while high-temperature or custom models may cost more. Bulk or OEM orders usually receive special pricing.

6. Type R vs Type S Thermocouple – What’s the difference?

Type R: Uses Platinum-13% Rhodium (Pt-13%Rh) as positive / Platinum as negative, slightly higher temperature limit (up to ~1700°C). Often used in industrial furnaces and high-temperature metallurgical processes.

Type S: Uses Platinum-10% Rhodium (Pt-10%Rh) as positive / Platinum as negative, slightly more stable at laboratory and kiln temperatures, widely preferred for precision applications requiring repeatable high-temperature measurements.

Both types are highly stable and corrosion-resistant, but Type S is generally more cost-effective for typical laboratory and kiln use.
