LE373 Ferrous Coating Thickness Gauge

Description

h2>The High-Capacity Ferrous Gauge That Set the Standard for the L600S

The LE373 was Kett’s electromagnetic coating thickness gauge for operators measuring non-magnetic coatings on magnetic substrates who needed to log large volumes of readings. It is no longer manufactured. The information below is provided for owners of existing units and for buyers identifying the current replacement.

What the LE373 Did

The LE373 used an electromagnetic probe to measure the thickness of paint, plating, lining, and other non-magnetic coatings on iron, steel, and other magnetic metals. It shared the measurement performance of the LE370 and added substantially greater on-board data capacity.

Built for ferrous substrates: Electromagnetic measurement of non-magnetic coatings on steel and iron, covering plated, painted, and lined parts.
Wide measurement range: Up to 2,500 µm, handling thick linings and heavy coatings as well as thin films.
100 application memories: Stored calibration curves for repeated jobs, so an operator could recall a setup without recalibrating.
Expanded data logging: Storage for roughly 39,000 measurement points, around thirteen times the LE370, with faster output to a PC for high-volume record keeping.

Why the L600S Replaces It

The LE373 was the data-logging member of the L3xx series, following the LE370 and the LE330 series before it. The current production model for all of this work is the L600S. It keeps the ferrous measurement that defined the series and adds a 2.7 inch full color display, storage for 50,000 records, and USB-C output for modern data transfer.

Looking for the current model? The L600S Coating Thickness Gauge replaces the LE373 and the entire L3xx coating gauge line.
