This Type S platinum rhodium thermocouple measures very hot temperatures. It gives steady, accurate readings from 0°C up to 1300°C. It’s a common sensor for checking conditions inside industrial furnaces, forges, and electric kilns.
Features and Benefits
- Platinum-10% Rhodium wire - This mix makes it more accurate. It lasts longer at high temperatures than K-type thermocouples.
- 0°C to 1300°C range - It works reliably in places too hot for most sensors. It’s good for metal and glass work.
- 150mm corundum ceramic probe - The tube protects the platinum rhodium wire. It keeps out dirt and prevents sudden temperature changes.
- Standard Type S connection - It works with many industrial temperature controllers and meters.
Applications
- Muffle furnaces and kilns - It helps you control heat for treating metals, firing ceramics, and lab tests.
- Glass manufacturing - It checks temperatures in melting tanks and ovens. This keeps products consistent.
- Smelting and foundries - It provides key temperature data for working with molten metals.
What It Is
This is an S-Type Platinum-Rhodium thermocouple with a 150mm probe. It is designed for accurate temperature measurement in demanding environments. The probe is constructed from Platinum Rhodium, a material known for its stability and high-temperature performance. It measures temperatures across a wide range, from 0 to 1300°C. The lead connects to a display gauge or temperature controller.
Key Uses & Applications
This Platinum-Rhodium thermocouple is specifically designed for use in muffle furnaces and electric kilns. Its robust construction and 150mm probe length make it suitable for monitoring high temperatures within these industrial and craft applications. The S-Type classification indicates its specific material composition and temperature characteristics, ensuring reliable readings in the specified environments.
How to Choose
When selecting a thermocouple, consider the intended application and temperature range. For muffle furnaces and electric kilns, an S-Type Platinum-Rhodium thermocouple is appropriate due to its 0-1300°C range. The 150mm probe length should be sufficient for immersion into the heating chamber. Ensure compatibility with your existing display gauge or temperature controller.
Grit / Spec Guide
This product is an S-Type Platinum-Rhodium thermocouple with a 150mm probe. It is rated for a temperature range of 0-1300°C. The material is Platinum Rhodium. It is suitable for muffle furnaces and electric kilns. There are no grit specifications associated with thermocouples; their performance is defined by material, type, probe length, and temperature range.
Care & Safety
Ensure the thermocouple probe is not physically damaged before use. For cleaning a water heater thermocouple, or any thermocouple, gently wipe the probe with a clean, dry cloth to remove soot or debris. Never use abrasive materials or harsh chemicals. If replacing a thermocouple on a gas fireplace, always follow the manufacturer's instructions carefully and ensure the gas supply is off before beginning work.

Q: What is the full temperature range of this Type S thermocouple? A: It's designed for continuous measurement in temperatures from 0 up to 1300°C (2372°F). For very brief periods, it can handle spikes up to 1600°C, but it's most stable within its recommended range.. Q: What are the probe and the internal wires made of? A: The outer protective tube is a 99% corundum ceramic, which is very resistant to thermal shock. The sensing wires inside are a platinum-rhodium alloy, which is the standard for Type S sensors and gives them their high-temperature accuracy.. Q: Can I install this in my muffle furnace? A: Yes, it's made for exactly that kind of equipment, as well as for electric kilns. The 150mm probe length and high heat tolerance make it a direct fit for many common furnace models.. Q: The ceramic probe seems fragile. What if it arrives broken? A: We pack them very carefully to prevent damage, but if it does arrive broken, just contact us and we will ship a replacement immediately. You should handle it with care during installation, as the corundum tube can crack under impact.. Q: Why choose this platinum-rhodium thermocouple over a less expensive Type K? A: A Type S thermocouple is much more stable and accurate at the very high temperatures found in kilns, especially over 1100°C. A Type K sensor can degrade and lose accuracy more quickly in that kind of extreme, continuous heat..
