LZ900 Integrated Dual Coating Thickness Gauge

The LZ900 Dual Coating Gauge: Now Consolidated Into the LZ990

The LZ900 measured coatings on both ferrous and non-ferrous metal from a single integrated probe, but required the operator to select the mode (FE or AL) by hand. It is no longer manufactured. Its measurement role is now part of the LZ990, a one-piece gauge that detects the substrate and selects the circuit automatically, with no mode to set.

What the LZ900 Did

• Dual-substrate measurement: electromagnetic and eddy current measurement of coatings on iron, steel, and non-ferrous metal, with manual mode selection (FE / AL) and both calibration substrates included.
• Integrated probe body: a single sealed handheld with a spring-loaded probe for curved and edged parts, no separate cable to manage.
• Field-ready range and accuracy: 0 to 1500 um (0 to 60 mils), accuracy of plus or minus 1 um below 50 um and plus or minus 2% above, on roughly 35 hours of battery life.

Why the LZ990 Replaces It

Your LZ900 measured both substrates but required you to select the mode by hand. The LZ990 detects the substrate automatically with no mode to set. For the same price, it also extends the range to 2000 um, adds onboard memory for roughly 1000 readings with statistics and lot functions, moves to 16 calibration channels, and adds USB and RS-232C output, none of which the LZ900 had. Accuracy is unchanged: the LZ900 already met the same specification.
