Coating Thickness Gauge Selection and FAQ

From:Linshang Time:2019/08/22 20:35:00 Browse:1089
Linshang Technology as a coating thickness gauge manufacturer provides high-precision painting thickness meter, also known as mil gauge or automotive (car) and dry film thickness (DFT) tester.

Coating or painting thickness gauges are used for measuring the paint thickness of material surface, controlling the manufacturing quality and inspecting the automotive or used-car paint. All kinds of painting thickness gauge, mil gage or car paint meter can be used for measuring the non-magnetic paint, coating, insulating layer and dry film thickness (DFT) non-destructively on ferrous or non-ferrous metal substrates such as copper, steel, iron or aluminum.

A digital paint thickness gauge is an important painting film and quality inspection tool when anodizing, galvanizing and applying zinc coating to metallic surfaces. Coating thickness gauge can be also used to measure the paint thickness and uniformity on used-cars, revealing repainted spots, identifying hidden damages and exposing undisclosed accidents. This function is very helpful when determining the actual value of a used-car. Powder coating thickness gauge is used for measuring powder coating thickness, it’s a magnetic or eddy current thickness gauge on powder-coated metal substrates.

III. FAQ about Linshang Coating Thickness Gauge

  1. 1. How long is the product guarantee?

    Linshang coating thickness gauge can be returned to the factory without any reason in 90days (No human damage and can be used for second sales).The supplier provide one year warranty and lifetime maintenance after-sales service.

  2. 2. What materials can be tested with Linshang coating thickness gauge?

    The Linshang coating thickness gauge uses both the Hall Effect and the eddy current principle. It is an iron-aluminum dual-use instrument that automatically recognizes the substrate and switches between iron-based and non-ferrous-based measurement modes.

    • It is suitable for measuring the thickness of non-magnetic coating ( paint, varnish, enamel, galvanized) on magnetic metal substrates such as steel, iron, etc.,

    • It is also suitable for measuring non-conductive coatings (coatings, anodized layers) on non-magnetic metal substrates such as copper,aluminum,die-cast zinc,etc. 

  3. 3. What are the similarities and differences between LS220H and LS221?

    • The same point:the measurement parameters of LS220H and LS221 are the same.The two meters can be used both for iron and aluminum,the range is 0-2000 microns.

    • Difference:The LS220H is an integrated type that can be operated with one hand.The LS221 is a split-type instrument that is more suitable for measurements in narrow spaces and higher or lower positions,making reading and operation more convenient.

  4. 4. What are the similarities and differences between LS221 and LS223?

    The same point: the probes of the LS221 and LS223 coating thickness gauges are connected to the main unit through an external line, which can measure some small spaces and higher or lower positions. The reading is more convenient.

    Difference:

    • The probe and main unit of LS223 coating thickness gauge are detachable. The LS223 is available in two range sizes. The probe of LS221 coating thickness gauge is non-removable.

    • The LS223 also supports automatic trigger boot during the test. The LS221 coating thickness gauge does not have this function. 

  5. 5. Is the LS223 equipped with two probes?

    The LS223 coating thickness gauge is a large-scale coating thickness gauge.The two probes can be individually selected.The probes can be configured according to your needs.The price of the two probes is different.The price of the F3N3 probe is slightly lower.For the F5N3 probe.

    • F3N3 range: iron-based, non-ferrous base are 0-3000 microns

    • F5N3 range: iron base 0-5000 microns, non-ferrous base 0-3000 microns

  6. 6. Do I need to calibrate the instrument before I use it?

    No, Linshang coating thickness gauge does not require calibration and can be used only by making zero adjustment.

  7. 7. In what conditions do we need to make zero adjustment?

    Several situations in which zero adjustment is recommended before testing:

    • Tested material substrate has been changed

    • The instrument has not been used for a long time

    • When the ambient temperature changes greatly

    • The instrument has been replaced with a battery

  8. 8. Does Linshang coating thickness gauge provide a measurement certificate?

    The Linshang coating thickness gauge can ensure the inspection by the authoritative metrology institute. If you need a metrology certificate, you can send it to a third-party authoritative metrology institute for inspection. Our company also provides the inspection service on behalf of the company.
