Seems to be working great, shorter lead time then what told. Highly recommend!

What material is the well made of? Could this unit be used to check surface mount magnetic thermocouples?
The CL100A series Dry Block Calibrator well is made of Stainless Steel and is meant for probes at least 4" long and would not be good for surface probes.

For the CL1000 Mini hot point Dry Block Probe calibrator, can these be supplied with more than one well style, say A and D? Can the wells be purchased separately from the dry block? If so please quote the calibrator with A type well and then price for D
Hi Glen,
Thank you for the inquiry. The wells are not interchangeable on the CL1000. They are integrated in to the assembly.
Please consider the DBCL series which has interchangeable wells.
