TRIDENT
1 instrument, 3 methods for thermal conductivity
(It's better to have options.)
Configure with multiple sensor options
"When all you have is a hammer, everything looks like a nail." The adage rings true in thermal conductivity characterization. It’s better to have options. Trident unleashes the power of three different transient methods with the ultimate toolbox for thermal conductivity measurement. MTPS, TPS and TLS all in one modular package. Choose the right tool for your samples. Choice is good.
MTPS
Fast, easy, and highly accurate. A single-sided, “plug & play” sensor suitable for testing solids, liquids, powders and pastes. Offers maximum sample versatility. Conforms to ASTM D7984.
TLS NEEDLE
Sheathed in stainless steel, the TLS Needle sensor offers maximum robustness in thermal conductivity testing. Conforms to ASTM D5334 and D5930.
FLEX TPS
A flexible double-sided sensor available in different sizes. Greater control over experimental parameters makes TPS ideal for more advanced users. Conforms to ISO 22007-2 and GB/T 32064.
How it Works
C-Therm's Trident system offers three different modes of operation in measuring the thermal conductivity of materials. The MTPS high precision method is the simplest and most versatile. The TLS Needle method provides maximum robustness for those sticky situations. The Flex TPS method provides the greatest flexibility over experimental parameters with C-Therm's flex sensors. Learn more about how each method works below.
Modified Transient Plane Source (MTPS)
Simple and Precise. The MTPS method employs a single-sided sensor to directly measure thermal conductivity and effusivity of materials. The MTPS method has the highest precision, highest sensitivity, shortest test time, and is the easiest to use among all three techniques.
Transient Line Source (TLS) Needle
The TLS method employs a needle probe to characterize the thermal conductivity of viscous and granular materials. It is the most robust sensor for thermal conductivity testing.
Transient Plane Source (TPS) Flex
The TPS method employs a double-sided hot disc sensor to simultaneously determine thermal conductivity, thermal diffusivity and specific heat capacity of materials from a single measurement. TPS provides the user the greatest flexibility and control over experimental parameters and avoids the use of any contact agents. Recommended for more experienced users.
