Our company focus is to provide accurate, fast, and cost effective measurements of many material properties using an ASTM method best suited to the type of material.
Thermophysical Properties Research Laboratory, Inc. (TPRL, Inc.) is a small business that
performs materials measurement and research for both government agencies and private
companies. TPRL, Inc. also performs joint research work with Purdue University into new
measurement methods and techniques. TPRL was created back in 1965 as part of Purdue University
to aid in the developement of the TPRC - CINDAS data book series. Since 1972 TPRL, Inc. has prepared
over 20 thesis, 200 publications, and over 6,100 technical reports. Research on the thermophysical
properties of materials (with special emphasis on solids) is performed from cryogenic temperatures
(-170 C) to very high temperatures. This research can be divided into two distinct types of
1. Contract research on determining properties of real materials of special interest to
particular organizations which involves stringent deadlines.
2.Fundamental studies of material properties and of measurement techniques which is
generally funded by a government agency, consortium of companies or an individual
The laboratory is located in the Purdue University Research Park where it occupies 3300
square feet of laboratory space. The laboratory was especially modified for precision
measurements. Special grounds for instrumentation, floating slab floors and air
conditioning for proper temperature and humidity control are provided. Machine shop
and electronic support are included as part of TPRL for instant access in order to facilitate
Each experiment is controlled through a PC, which also collects, analyze, and display the
data from the experiments. Each of these computers is linked to a file server for quick and
easy assembling of data for each report. Standardization facilities directly traceable to
NIST standards are also an integral part of TPRL.
TPRL provides consulting services on thermophysical properties including theory, current
measurement practices, modern materials etc. for scientists and engineers involved in
advanced heat transfer applications.
