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.
  
  
• All BRK meters and probes ship direct from the manufacturer and require 5-10 days for shipping.

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 µm) up to 13 mm (13,000 µm), 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.
