Description
The H4000 Portable Hardness Tester is a rebound device capable of measuring the hardness of a variety of metals and alloys with either flat or round surfaces. This instrument has an easy-to-read digital LCD display, memory function (storage capacity: 999 readings) and readily interchangeable impact probes.
While obtaining data at the test site, the built-in printer can be actuated to obtain a printout, or the unit can be connected to a computer to analyze and/or print data as desired. Leebs hardness numbers can be automatically converted to HLD, HRC, HRB, HB, HV, and HS for a menu of selected metals and alloys.An optional program is available for producing and adding to the menu custom conversions for other metals and alloys of the customer's choosing.
