About Us

We began manufacturing and selling thermal conductivity measuring equipment in 1999, and today,
we are one of Japan’s leading manufacturers of thermal conductivity measuring equipment.

Currently, in addition to selling equipment, we also engage in measuring thermal conductivity/thermal
diffusivity and research on a contract basis.

Do you have any troubles like these?

✓ You need to measure thermal conductivity or thermal diffusivity of graphite sheets and other materials that are difficult to evaluate with conventional methods.
✓ You need reliable thermal data for thin films or microscopic areas.
✓ You want to evaluate soft, low-thermal-conductivity materials such as thermal pads, resins, or thermal grease.
✓ You need thermal measurement or analysis but are not ready to purchase equipment.

Let us handle it!

Our Strength

Thermowave Analyzer TA

 
The Thermowave Analyzer TA we developed is a device which analyzes the thermal characteristics of materials.
This product was developed through joint research with national research institutes and universities, so we can recommend its precision and reliability with confidence.
The measurement range extends from organic films to diamond, and it is capable of measuring thermal conductivity and thermal diffusivity by measuring the thermal response of a material with laser diodes and infrared radiation.
 
The Thermowave Analyzer TA made it possible to measure the thermal conductivity of graphite sheet used in heat management for power semiconductors and IT equipment, which was difficult to achieve with conventional measurement methods.
Understanding thermal conductivity has attracted attention as an important factor in reducing the power consumption of equipment.
 
Our thermal conductivity measuring equipment and contracted measurement techniques provide support for heat management that is essential to the electronics, automotive, and aerospace industries as they continue to advance.
 
 

OTHER MEASUREMENT DEVICES

We offer a variety of other thermal conductivity measuring devices.  
 

Steady State Thermal Conductivity Meter SS-H/M20

Thermal pads, plastic resins, thermal grease, etc. This device is suitable for measuring soft materials with lower thermal conductivity.  
 

Thermal Microscope

Thermally conductive filler, superconducting thin films, etc. This device is capable of measuring thermal conductivity in small areas like a microscope.  

Fiber Orientation Analysis System <Thermal Evaluation of FOD>

This device can measure the fiber orientation in fiber reinforced plastics such as CFRP. It is capable of quick and non-destructive testing. Devices such as this are promising for the aerospace and automotive sectors.

Message

In Japan, we receive many measurement requests from leading companies and universities.
We led the establishment of JIS R 7240, a Japanese standard for measuring the thermal diffusivity
of graphite sheets, and received the Minister of Economy,
Trade and Industry Award for our contribution to industrial standardization.
