3M Taiwan

We use TCi extensively for our product development and to analyze products available on the market. TCi provides fast and accurate results. We are very confident in this instrument.”

Wayne Chen,
3M Taiwan (Sector: Textiles)


The main benefit of the TCi to our testing lab is its ease of use and short test times. It allows us to get accurate results as quickly as possible and with excellent repeatability. Our test times are only a fraction of what they are using steady state methods. Equally important, the service level has exceeded our expectations."

Dr. Ernest Wolff,


We wanted something that was going to measure small volumes and do it in a rapid and easy format and the TCi Thermal Conductivity instrument was perfect for our needs. The thing I like most about the TCi is it is extremely easy to use."

Dr. Steven Oldenburg,

American Aerogel Corporation

The technology has allowed us to provide accurate quality assurance for our products that wasn’t previously attainable by any other methods. The instrumentation has been a rapid and consistent means for our company to ensure that every product leaving our facility meets our rigid specifications. It has given us a competitive advantage. In fact, we’ve been awarded contracts partly due to the superiority of the instrumentation over every other means of quality testing."

Robert Mendenhall,


...outstanding technical support and fundamental understanding of the mathematics and engineering complexities of heat transfer issues has greatly impressed me."

Dr. Keith Kociba,

Thermoelectrics Manufacturer

While other thermal conductivity measurement techniques suffer from slow speed, difficult sample preparation, and/or accuracy limitations due to model inputs, the C-Therm TCi’s strength lies in its elegant approach to a notoriously difficult measurement. The C-Therm TCi has helped us rapidly screen processes for manufacturing thermoelectric materials. C-Therm’s product support is truly world class. Whether supporting existing platforms or extending system capability through advances such as the thin film module, C-Therm stands out as a vendor we have grown to count on."

Vertec Polymers

C-Therm TCi probe is very easy to use, very versatile. I can do my material testing within a couple of minutes. I don't have to spend all day and all the time to adjust thermal conductivity measurement. And time is important to me, to just know the number and move on; and this probe allows me to do the testing whenever I need, as I need, and I can do it quite quickly."

Dr. Pradeep Rai,
Senior Research Scientist

Axel Products

As a contract test lab, we need dependable instrumentation so we can serve our customers. After many years using a different transient method, we now use the C-Therm TCi Thermal Conductivity Analyzer and it works great!"

Kurt Miller,


The C-Therm TCi Thermal Conductivity Analyzer has provided our group a fast, accurate capability to test the thermal conductivity of our polymers with C-Therm’spatented high-precision MTPS sensor. The instrument has become very popular within our group for its quick easy reliable measurement and the support from C-Therm has exceeded our expectations. We recently upgraded the unit with the new robust TLS module for work on polymer melts."

Jose Fonseca,
Expert in Thermodynamics

Université du Québec à Trois-Rivières

We purchased C-Therm's TCi Thermal Conductivity Analyzer originally to characterize the thermal conductivity of metal hydrides. We liked that it could operate in a wide range of environments and test different materials. It provides accurate, unambiguous thermal conductivity results. What I've really come to appreciate about it is how easy it is to operate. Our students can train on it for 30 mins and be proficient in being left on their own in running their samples. We have many visiting scholars that used C-Therm's TCi for many types of samples. This equipment is really versatile."

Dr. Jacques Huot,

Eaton Cooper Power Systems

My C-Therm TCi is working well and it has been used to generate valuable data. The instrument is a great addition to our lab's testing capabilities."

Richard Baumann

Seaforth Geosurveys Inc.

Seaforth Geosurveys turned to the C-Therm TCi for effective thermal conductivity characterization in our exploration vessel’s on-board lab. The portability and ease of use of the instrument allowed our technicians to rapidly measure thermal conductivity of our geological core samples accurately and consistently in a 24-7 operation. As a Nova Scotia based company working worldwide, we were pleased to have a local, made in Atlantic Canada solution for our project requirements. We would recommend the TCi for any research or screening with a focus on geological and/or in-situ applications, and we will continue to utilize it on new exploration missions.”

David Lombardi,


The device is working perfectly."

Dr. Christian Heyde,
Sport Science Manager

College of Chemical Engineering, China University of Petroleum

Our lab purchased C-Therm's TCi in 2016. The instrument is very easy to operate and the software is very easy to learn. After a long period of experimental data comparison, we find the test data from the TCi is very accurate, which has greatly helped our experiment. And the company's after-sales service is very satisfying too. If we experience any problem, we can receive reply and have it solved right away.”

Dr. Zhenfeng Sun,

Bureau Veritas Guangzhou

We offer ASTM D7984 testing with TCi in our lab. We were impressed with the service and support provided by C-Therm.”

Martin Ho,
Manager - Softline Testing

IATRC, Tianjin University of Commerce

Our centre purchased a C-Therm TCi in 2018 for thermal conductivity testing of experimental materials such as nanofluids, refrigerants, fruits and vegetables. The instrument is easy to learn and requires only less than 20 minutes of training for students to be proficient in operation. Testing results of several experiments were compared with the literature, and the instrument shows a very high accuracy. In addition, the design of the TCi sensor and the controller, separable and connected by a data line, is very helpful for our experiment, which makes it convenient for us to carry out tests in different temperature and humidity environment."

Aiqiang Chen,

University of Arizona, Tuscon

The TCkit from C-therm is simple-to-use and set up yet sophisticated in thermal analysis of wide variety of materials such as low 'k' metals, rocks and almost all ceramics. This instrument is beautifully constructed that caters from enthusiastic students to learning and understanding the thermo-physical measurement of materials in the laboratory, to mature scientists wishing to characterize their novel materials. The Kapton coated double spiral Ni sensor is robust yet flexible to ensure efficient contact between the surfaces. The short measurement time enables multiple measurements within minutes and accurate values of thermal conductivity and thermal diffusivity can be obtained. Overall, great experience. Thank you C-therm!"

Pratish R. Rao,
Graduate Studies Supervisor

Pen-Tung Sah Institute of Micro-Nano Science & Technology, Xiamen University

We use the TCi Thermal Conductivity Analyzer to test various materials. In comparison, the instrument is easy to operate and the test speed is fast. Many students can operate independently and save a lot of time. C-Therm also provides very good support services. If we have any question, we can always get a quick response. We enjoy the cooperation very much!”
