●
The special work tube design provides a much
higher temp. uniformity than is typical for a furnace
of this size
●
The metallic worktube is earthed for operator
safety when testing metal sheathed mineral
insulated mineral thermocouples
●
Weighing in at only 8kg, the rapid heat up and
stabilization of the PTC 12/20 make it ideal to set
up and use in the lab or on site.
