400°CVT DVT400

This attachment allows ESR measurements at a preset temperature from 50 to 400°C, using liquid nitrogen (below ambient) or air (above ambient).
The desired temperature can be set from the PC using a USB cable to an X3 series instrument.
Improvements from previous models include speed and stability of temperature. Use of the light irradiation attachment and the Mn2+ marker is possible, and it is suitable for routine measurements.
Safety has been further improved with inclusion of a check system for liquid nitrogen in Dewar and for water circulation against freezing.
