See the temperature profile inside the material, not just a number at one point.
Calornet builds ultra-high-temperature distributed temperature sensing for labs studying material synthesis, crystallization, and critical minerals. One fiber, in contact with the sample, resolves the full thermal profile across every phase as it forms.
If your work depends on knowing what is happening thermally inside a sample as it transforms — not just a surface reading — this is built for your experiment.
Departments studying ultra-high-temperature ceramics, refractory alloys, and phase transformation behavior who need thermal data that matches the resolution of their microstructural work.
Teams developing extraction, refining, or synthesis routes for critical minerals, where knowing the real thermal profile through a reactor or crucible changes process decisions.
Groups growing or synthesizing crystals and advanced ceramics who need to resolve solidus, liquidus, and recalescence events along a sample, not just at one probe location.
Traditional thermocouples give you one point. Pyrometers give you a surface, and only if you know the emissivity. Our fiber gives you a continuous profile, in contact with the material, through the phase change itself.
| Method | Measurement | Contact | Limitation |
|---|---|---|---|
| Thermocouple | Single point | Direct contact | No spatial profile; drift and degradation at extreme temperatures |
| Pyrometer | Surface, single or few points | Line-of-sight, no contact | Intensity-based; needs known emissivity, blocked by smoke, dust, or geometry |
| Calornet fiber DTS | Continuous profile, thousands of points | In contact with the material | Resolves phase-by-phase behavior along the full sample or reactor length |
A single optical fiber is placed in direct contact with the material or reactor, following the path where thermal behavior matters most.
We interrogate the fiber and capture temperature-dependent backscatter at thousands of points along its length, in a single measurement pass.
The result is a continuous temperature profile that reveals melt onset, liquidus, recalescence, and solidus behavior across the sample — not just at one probe.
Calornet LLC is a scientific consulting and technology firm based in Rolla, Missouri. We work directly with university research groups and research-driven companies to bring distributed, in-contact temperature sensing to experiments where traditional instrumentation runs out of resolution — or runs out of temperature range.
It's a measurement technique that uses a single optical fiber, placed in contact with a material or reactor, to resolve temperature continuously at thousands of points along its length in one measurement pass — rather than at one spot, as with a thermocouple.
A thermocouple reports temperature at a single junction. A distributed fiber captures the full thermal profile across a sample or reactor length, revealing melt onset, liquidus, recalescence, and solidus behavior that point sensors simply can't see.
Our systems are built for ultra-high-temperature research: material synthesis, crystallization, and critical mineral processing. Talk to us about your specific temperature range and sample geometry.
University labs and research-driven companies working in ultra-high-temperature ceramic synthesis, critical mineral extraction and refining, crystal growth and solidification studies, refractory alloy development, and additive manufacturing.
Yes — the fiber is designed for direct, in-contact placement in demanding thermal environments where thermocouples and pyrometers lose accuracy, run out of range, or are blocked by smoke, dust, or geometry.
Reach out directly — we typically start with a short conversation about your sample, temperature range, and what your current instrumentation isn't showing you.
