TEMPOS Thermal Properties Analyzer

The TEMPOS Thermal Properties Analyzer is a cutting edge instrumentation system developed by METER Group for rapid, accurate measurement of a wide range of thermophysical properties—including thermal conductivity, thermal resistivity, thermal diffusivity and volumetric specific heat. It addresses the traditional limitations of thermal needle and steady state methods (such as long heating times, contact resistance, moisture movement) by using advanced algorithms, proprietary sensor design and optimized test protocols.

With compliance to major standards (ASTM D5334 and IEEE 442) and support for moist, frozen and fluid materials, TEMPOS enables valid data collection across soil, concrete, insulation, plastics, lubricants, food, geological and even biomedical domains.

Key Feature

• • Supports measurement of thermal conductivity, thermal resistivity, thermal diffusivity and volumetric specific heat in one instrument.
• • Extremely short measurement time: typical read in about 1 minute (versus 10 15 min for many older systems).
• • Compliant with ASTM D5334 and IEEE 442 standards for thermal needle testing.
• • Portable yet rugged — suitable for both field and lab use; equipped with sensors (needles) engineered for specific material types.
• • Automatically detects connected sensor type, applies optimized algorithm, compensates for temperature drift.
• • Supports moist, frozen and liquid materials—short heating times minimize moisture migration or evaporation during test.
• • Data storage and download capability: stores raw and processed data, supports mini USB interface for export.

Technical Specification

Applications

• • Soil and geotechnical investigations: measure thermal properties of soils, permafrost, frozen ground for civil/geo engineering.
• • Building materials & concrete: assess insulation, concrete thermal conductivity, resistivity for building physics/energy auditing.
• • Food, plastics, lubricants: evaluate thermal behaviour of process materials under varying states (solid, liquid, frozen).
• • Research & materials science: advanced measurement in thin films, composites, geological or biomedical samples. (Note: TEMPOS referenced in tissue thermal property study)
• • Field or laboratory use: Portable measurement enables on site audits, field verifications and laboratory validations.

Benifits To Users

• • Rapid, accurate measurement means higher throughput and reduced wait times—ideal for time sensitive testing or field campaigns.
• • Versatility across materials and states (solid, liquid, frozen) means fewer specialized instruments needed.
• • Compliance with major standards gives confidence in data validity for engineering or research certification.
• • Portable yet professional instrumentation enables use both in the lab and in the field—saving logistic costs.
• • Automated sensor recognition, optimized algorithms and user friendly interface reduce training/time to use.

Best Practice /Consideration

• • Ensure sensor needle is properly inserted into the material under test with good thermal contact—air gaps adversely affect results.
• • For moist or frozen materials, make sure the test environment is thermally stable (avoid drafts, sunlight or fluctuating ambient) to minimize error.
• • Choose the correct probe/needle type for material type and desired property range (e.g., single vs dual needle, length).
• • Store data and review raw PLUS processed output to verify stability and repeatability (e.g., repeat readings).
• • Maintain battery charge, clean sensors after use, and keep firmware/logic updated if applicable.
