Environmental TEMPOS Thermal Properties Analyzer


The new TEMPOS Thermal Properties Analyzer from the Meter Group replaces the Decagon KD2 in our inventory. It is the newest model from that manufacturer. The TEMPOS model represents a complete redesign and the result is a much-improved, faster instrument. 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 food, plastics, lubricating oil, and even human tissue.

New technology—new possibilities

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 10-15 min.).

Takes compliance to a whole new level 

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 to measure frozen materials and even fluids. No other analyzer on the market can measure frozen or wet materials accurately.

One minute changes everything

Ambient temperature changes of a thousandth of a degree per second, the sun warming the soil for example, destroy the accuracy of thermal properties calculations. Unique from all other thermal needle systems, the TEMPOS corrects for the linear temperature drift that causes erroneous readings. New proprietary algorithms allow the TEMPOS to make these measurements in as little as one minute (ten minutes for ASTM-compliance). And, these algorithms will eventually allow the TEMPOS to measure previously impossible-to-test highly porous materials such as insulation.

Simply the best

Forty years of expertise on heat and mass transfer have enabled us to engineer the most simple, easy-to-use instrument possible. Unlike competitor instruments, which use a one-sensor-fits-all type system, the TEMPOS automatically optimizes the reading for your material at the push of a button. And it’s ready to use, straight out of the box. Just insert the needle, select your material type, and start measuring.  It’s that easy.
