Super Fine Sheathed Thermocouples
SUPER FINE MINERAL INSULATED THERMOCOUPLE
Features
The super fine sheathed thermocouples have a sheath diameter of φ0.08 mm, the smallest diameter in the world, and whose response time is 1 ms or less. Since it can be bent freely at any angle, accurate and quick temperature measurement of small targets at extremely narrow places is possible. We also have products of φ0.10, φ0.15, and φ0.25.

- *1：
We cannot recommend a long length since a longer length has a bigger roundtrip resistance value, which is a factor in measuring errors.
- *2：
For a short time (disposable), up to approx. 1,000℃ can be measured.
- *3：
Normal temperature to 100℃ of boiling water
- ●
The response speeds have been described referring to testing based on our experiment, calculated values, etc.; therefore, they are not guaranteed values.
(The standard one has a bigger sheath tip than others. If you desire one with the same diameter, contact us in advance.)
