Welcome to Kett - Tomorrow's Testing Today
Eddy current coating thickness gauge for coatings on aluminum, copper, and brass, no longer in production.
The LH300 measured insulating coatings on non-magnetic metal substrates from a pocket-size handheld unit. It has been succeeded by the L600S, which carries the same non-ferrous measurement with far greater memory, a color display, and USB-C output.
$1,595.00
The LH300 was Kett’s original eddy current pocket coating thickness gauge for measuring insulating coatings on non-magnetic substrates. It is no longer manufactured. The information below is provided for owners of existing units and for buyers identifying the current replacement.
The LH300 used an eddy current probe to measure the thickness of paint, anodizing, resin, and other insulating coatings on aluminum, copper, brass, and other non-magnetic metals. Operators worked from one pocket-size unit with a single-contact probe that applied constant pressure for repeatable readings.
The LH300 was the original of the line, followed by the LH330, LH370, and LH373 series. The current production model for all of this work is the L600S. It keeps the non-ferrous measurement that defined the LH300 and adds a wider measurement range, 100 application memories, storage for 50,000 records, a 2.7 inch full color display, and USB-C output.
