The Verimation (K.J. Law) M4900C is known for its accuracy, simplicity, ruggedness and reliability.

• No complicated bells and whistles
• M4900C simply measures eddy current conductivity
• Well suited for shop and field use.
• The most rugged and reliable instrument, probe and cable
• Easily used by shop and warehouse personnel

The major application for the M4900C is measuring the conductivity of aluminum alloys. It automatically tracks the temperature coefficient. The M4900C works well on rough or finished surfaces including forging, castings, sheet stock, and small parts with reasonable mass.

Typical Applications:

• Sorting mixed non-ferrous metals and alloys
• Evaluating material alloy, hardness and uniformity of heat treat
• Measuring absolute conductivity
• Detecting heat damage to aircraft surfaces and structures
• Checking Aluminum alloy for aging
• Testing for proper aluminum
