Q3. FAQS
A. What Is The Measuring Principle Of Coating Thickness Gauge? What Do "Fe" And "Nfe" Stand For ?
Coating Thickness Gauge (Except Ls225 Plating Thickness Gauge) Adopts Magnetic Induction And Eddy Current Principle.
The Coating Thickness Gauge Can Automatically Recognize "Fe (Ferrous)" And "Nfe (Non- Ferrous)" Two Different Metal Substrates. It Is Recommended To Use The "Fe (Ferrous)" Mode For Measuring Magnetic Metal Substrates (Such As Steel, Iron) And The "Nfe (Non- Ferrous)" Mode For Measuring Non-Magnetic Metal Substrates (Such As Aluminum, Copper). For The Substrate Type, You Can Also Select The "Auto" Mode. The Coating Thickness Gauge Can Automatically Recognize The Substrate Type And Switch The Measurement Mode.

B. What Is The Response Speed Of Linshang Coating Thickness Gauge ?
Linshang Coating Thickness Gauge Response Speed Is Very Fast Compared With Other Coating Thickness Gauges On The Market. It Uses A Highly Sensitive Probe, Measurement Can Be Completed In 0.5S.

C. What Are "mil" And "um"? How To Convert The Coating Thickness Gauge Unit ?
The Terms "Mil" And "Micron" Are Units Of Thickness Measurement.
In The English System, 1 Mil = 0.001 Inch
In The Metric System, "1 Μm" Means A Micron, 1 Μm = 0.001 mm
To Convert Mils To Microns: 1 Mil = 25.4 Μm

D. How To Calibrate Coating Thickness Gauge ?
Select An Uncoated Workpiece As The Calibration Substrate; It Must Be Made Of The Same Material As The Workpiece To Be Tested.
Press And Hold The Probe Firmly Against The Substrate, Then Press The Button.
Follow The Prompt To Lift The Probe; The Calibration Will Be Successful Once Completed.
Recalibrate The Device Whenever Switching To Different Materials, Testing Environments (E.G., Temperature, Humidity), Or Other Conditions.

Q4. What Is A Coating Thickness Gauge ? 
Coating Thickness Gauge Can Measure Non-Magnetic Coatings On Various Magnetic Metal Substrates (Such As Steel, Iron, Etc.) And Non-Conductive Coatings On Non-Magnetic Metal Substrates (Such As Aluminum, Copper, Zinc, Etc.) . Coating Thickness, Paint Thickness, Or Dry Film Thickness (Dft) Is An Important Variable That Affect Product Quality, Process Control, And Cost Control. We Offer A Range Of Coating Thickness Gauges Tailored To Different Industries. If You'Re Looking For The Most Suitable Product For Your Specific Industry, We'Re Here To Help.

Q5. How Does A Coating Thickness Gauge Work ?
The Most Common Measurement Principles Include Electromagnetic Induction And Eddy Current, While Ultrasonic And Beta Backscatter Methods Are Also Used For Specific Applications.

Some Coating Thickness Testers Utilize The Electromagnetic Induction. This Method Is Used To Measure Non-Magnetic Coatings (Such As Paint, Plastic, And Zinc Plating) On Ferromagnetic Substrates (Such As Steel And Iron). The Probe Contains A Permanent Magnet Or An Electromagnetic Coil, Which Generates A Magnetic Field. When The Probe Approaches A Ferromagnetic Substrate, The Magnetic Flux Density At The Probe Changes, With The Amount Of Flux Being Inversely Proportional To The Distance Between The Probe And The Substrate.

Other Paint Thickness Gauges Operate On The Principle Of Eddy Current. It Is Used To Measure Non-Conductive Coatings (Such As Oxide Layers, Paint, And Plastic) On Non-Ferromagnetic Metal Substrates (Such As Aluminum, Copper, And Stainless Steel). The Probe Contains A Coil That Is Energized With An Alternating Current, Generating A High-Frequency Magnetic Field. When The Probe Approaches A Conductive Substrate, It Induces Eddy Currents Within The Material. The Strength Of These Eddy Currents Is Inversely Proportional To The Distance Between The Probe And The Substrate.

Q6. Why Dry Film Thickness Measurement Is Important ?
Using A Coating Thickness Gauge For Regular Dry Film Thickness (Dft) Measurement Is Crucial, As It Directly Affects Opacity, Appearance, And Protective Performance. Proper Thickness Guarantees Protection Against Corrosion, Uv Degradation, And Wear, Preventing Premature Failures Or Adhesion Issues. Applying Too Much Coating Can Also Be Detrimental That Can Lead To Excessive Drying Time, Cracking, And Flaking Of The Paint Film. Coating Thickness Measurement Will Monitor The Paint Process And Maintain The Appropriate Coating Properties. Many Industries, Including Automotive, Aerospace, And Marine, Adhere To Strict Astm And Iso Standards, Making Accurate Measurement Essential For Compliance. Additionally, Optimizing Coating Thickness Helps Reduce Material Waste And Production Costs While Maintaining Aesthetic And Functional Properties, Such As Uniform Surface Finish And Adhesion. In Both Manufacturing And Maintenance, Using A Dry Film Thickness Gauge Ensures Consistent Quality Control, Extends The Lifespan Of Coated Surfaces, And Enhances Overall Performance.

Q7. How To Use A Digital Paint Thickness Tester ?
Before Test, You'D Better Use Calibration Standards Or Zero-Calibration On An Uncoated Substrate To Ensure Measurement Accuracy. Then You Can Follow These Steps Below:
* Ensure The Test Surface Is Clean, Dry, And Free From Dust, Oil, Or Debris.
* Turn On The Paint Thickness Tester And Select The Appropriate Measurement Mode (Fe, Nfe, Fe/Nfe) Based On The Substrate Material.
* Place The Probe Perpendicular To The Coated Surface And Apply Gentle Pressure To Ensure Full Contact.
* The Result Will Be Displayed On The Screen.
