Coating Thickness Gauge

The BRK CTN-300 Coating Thickness Gauge is designed for versatile, high-precision measurement of coating layers on a wide range of substrates. Ordering Notes: BRK CTN-300 meter and probes are sold separately. Please select the desired probe for your specific application when purchasing this meter. It combines both magnetic induction and eddy current measurement principles with intelligent calibration algorithms to deliver accurate, consistent results from ultra-thin decorative coatings to industrial-grade protection layers. Compatible with an array of specialized probes, the CTN-300 handles ferrous, non-ferrous and aluminum substrates as well as complex curved surfaces such as pipes, screws and small components. Its broad measurement range and robust feature set make it suitable for manufacturing quality control, metal processing inspection, plating and anodizing verification, and corrosion protection checks in demanding industrial environments. Extensive Measurement Range Supports coating thickness measurement from 0.003 mm (3 um) up to 13 mm (13,000 um), covering a wide spectrum of coating types and thicknesses. Multi-Probe Compatibility Works with up to 13 dedicated probes including magnetic, non-magnetic, high-temperature and right-angle variants for maximum versatility. Magnetic Induction & Eddy Current Technologies Automatically detects substrate type (ferrous or non-ferrous) and applies the correct measurement principle for accurate results. High Precision & Intelligent Calibration Advanced sensing algorithms and automatic calibration routines provide reliable, repeatable measurements with minimal user setup. Versatile Measurement Modes Supports single measurement, continuous scan and statistical functions (average, max, min, count, standard deviation) for flexible inspection workflows. Robust Data Handling Built-in data storage with export capability and high/low limit alarms for quality control and reporting. Portable & Field Rated Durable metal housing and rechargeable lithium-ion battery support extended use in workshop and field environments. Typical Applications Industrial painting and powder coating inspection Plating, anodizing and surface treatment verification Automotive and aerospace coating quality control Marine and shipbuilding corrosion protection monitoring Manufacturing and fabrication process inspection
