Thermal Analyzer

There’s never been a thermal properties analyzer that gives accurate measurements under all conditions. Small sensors are fragile and face contact resistance. Large sensors and high-priced, steady-state methods, require long heat times, which drive moisture away from the sensor and alter the reading. Alternative instruments use one standard equation without making any adjustments for real-world conditions—plus they’re bulky and expensive. There’s simply been no convenient or affordable way to measure accurately. Until now.

Accurate readings at top speed

The new TEMPOS is different. We’ve ripped up everything in our thermal properties analyzer and reinvented it from the ground up to give you higher accuracy in much less time, at a price you can afford. How? Accurate thermal properties measurements have always been about complex mathematics. Recent scientific breakthroughs in how these complex equations are solved have enabled not only higher accuracy, but also allowed us to calibrate using significantly improved data sets—making this instrument more accurate than any other in its class. Not only that, improved proprietary algorithms enable the TEMPOS to make these measurements with an incredible one-minute read time (versus the usual 10 to 15 min).

Thermal properties analyzer takes compliance to a whole new level

The ASTM 5334- and IEEE 442-compliant TEMPOS is engineered using ISO 2008 standards. It takes accurate readings of thermal conductivity, thermal resistivity, thermal diffusivity, and specific heat in many material types across multiple disciplines, from soil and concrete to insulation, food, plastics, lubricating oil, and even human tissue. The new TR-4 needle is designed specifically to be compliant with IEEE specifications.

Each needle produces only a discrete amount of heat, virtually eliminating the moisture movement (or free convection in liquids) that could alter a reading. Short heating times mean you can use the TEMPOS thermal properties analyzer to measure frozen materials and even fluids. No other analyzer on the market can measure frozen or wet materials accurately. 

The Thermal Dryout Curves Analyzer is a high-precision laboratory instrument designed to study soil thermal properties and moisture dynamics under controlled heating/drying conditions. It enables accurate measurement of soil thermal conductivity, temperature distribution, and moisture release rates as the soil dries. This information is critical for understanding soil-water-thermal interactions, irrigation management, geotechnical studies, and environmental research.

It uses advanced sensors and software to record real-time temperature and moisture changes, producing thermal dryout curves that illustrate water content reduction under varying temperature gradients. The analyzer is ideal for research laboratories, agricultural institutes, and geotechnical testing facilities.

The VARIOS system from METER Group is a laboratory instrument designed for the automated generation of thermal­dry-out curves—that is, measuring how thermal conductivity (or thermal resistivity) of a soil or other porous medium changes as it dries.

Traditionally, constructing a thermal dry-out curve has been labor-intensive: large sample preparation, repeated weighing, manual measurement of thermal properties, lots of manual data-entry and curve-fitting. The VARIOS simplifies this by combining continuous weight measurement (to track moisture loss) with thermal conductivity measurements at intervals (while the sample dries) and automated software analysis.

It supports two measurement modes (continuous or point-by-point) and is compliant with major industry standards such as IEEE 442‑2017 and ASTM D5334.

This makes it especially useful for labs doing soil-thermal research, underground cable backfill/soil thermal resistivity studies, geotechnical/hydrogeological research where moisture changes influence heat transfer, and more.
