Compact Vacuum Sensor for Vacuum Insulation Materials

We have developed a compact vacuum sensor that uses thermal conduction to check the performance of vacuum insulation materials.
It is significantly smaller than conventional vacuum sensors and vacuum gauges, making it ideal for embedded applications.
Also, since it is equipped with a compensation sensor, accurate measurements can be made over a long period of time.


– Compact, can be installed in tiny spaces
– Fast response
