Industry-proven low loss dielectric test solution
- Ideal for evaluating low loss dielectric materials with tan δ 0.01 or less.
- Easy operation: simply inserting a rod-shaped sample into the insertion hole
- Efficient and reliable measurement with permittivity measurement software
- Robust hardware provides reproducible measurements over the years
- Powder measurement (option)
The TM resonator is a highly reliable solution that has been used extensively by many companies and research institutions for over a quarter of a century since our company began selling for the first time in Japan. With the extremely high Q value (over 10,000, typical) of the resonator itself, it is possible to accurately evaluate low loss materials with tan δ of 0.01 or less. Furthermore, since the measurement procedure is simple, you can efficiently measure materials with high repeatability. You can simply insert the rod-shaped sample into the sample insertion hole in the upper part of the resonator, and just click "measure". The measurement software guides you through the measurement with step-by-step explanation, with which you can obtain the correct measurement result from the beginning.

Even with a TM resonator designed for powder/liquid measurement, rod-shaped materials can still be measured (upward compatible).
A standard TM resonator can be upgraded later for powder/liquid measurement.
When measuring powder samples, we recommend using the software with the powder measurement option.
