The HTD1500 and HTD4000 Case Hardness Depth Analyzers from CISAM-ERNST measure the depth of heat treatment without destroying the part, using the patented Ernst load-penetration curve principle.

The HTD1500 and HTD4000 are non-destructive analyzers for case hardness depth measurement. They use the patented Ernst principle, based on evaluation of the load-penetration curve and a tested calculation algorithm.
The system determines the depth of heat treatment without sectioning, polishing, mounting and microhardness profile testing, so production batches can be tested without scrapping the tested parts.
The case depth value is shown directly on an 8.4-inch touchscreen, together with the schematic curve, hardness curve, statistics and curve overlay.
