LZ990 Integrated Coating Thickness Gauge

One Gauge for Every Substrate: No Probe Swap, No Mode Switch

Coating inspection often means two tools: one for paint and plating on steel, another for coatings on aluminum and other non-ferrous metal. The LZ990 replaces both. It reads the substrate automatically and selects the correct measurement circuit on its own, so a single one-piece gauge handles ferrous and non-ferrous parts as you move down the line.

Solving Everyday Inspection Challenges

• Mixed substrates on one workflow: Automatic substrate recognition switches between electromagnetic and eddy current measurement with no operator input, so you stop sorting parts by metal type.
• Curved and edged parts: A spring-loaded probe with edge guides and a V-cut sensor guide seats cleanly on pipes, tubing, and edges where flat-faced gauges struggle.
• Recordkeeping and traceability: Onboard memory holds roughly 1000 readings, with statistics and lot functions built in, then sends data to a PC over USB or to a printer over RS-232C.
• Repeat jobs with set tolerances: 16 calibration channels (8 electromagnetic, 8 eddy current) store your setups, and a lower-limit alarm flags any reading that falls short.

Built for the Shop Floor and the Field

The LZ990 measures from 0 to 2000 µm (0 to 80.0 mils) with accuracy of plus or minus 1 um below 50 µm, plus or minus 2% from 50 to 1000 µm, and plus or minus 3% above that. Runs on two AAA batteries with up to 60 hours of battery life, fits the hand for long inspection sessions, and ships with a zero calibration holder, calibration foils, carrying pouch, wrist strap, and manual. Coverage is backed by Kett’s One-Year Total Care warranty on parts and labor, with maintenance agreements available.

Need a printout right at the part? The L500 Coating Thickness Gauge puts an integrated thermal printer in the same handheld body for on-the-spot documentation.

Need interchangeable probes and a larger color display? The L600S Coating Thickness Gauge moves up to a swappable-probe platform for awkward geometry and high-volume work.
