The dry film gauge is a commonly used coating thickness testing instrument. The article details the advantages and application of the dry film gauge.

The dry film gauge has the characteristics of small measurement error, high reliability, good stability and easy operation. It is an indispensable coating thickness testing instrument for controlling and ensuring product quality. It is widely used in manufacturing, metal processing industry, chemical industry, inspection areas such as commodity inspection.

The dry film gauge can non-destructively measure the non-magnetic coating thickness (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic metal substrate (such as steel, iron, alloys) and non-conductive coating thickness (such as: enamel, rubber, paint, plastic, etc.) on the non-magnetic metal substrate (such as copper, aluminum, zinc, tin, etc.). The following is a detailed introduction to the advantages and application of the LS220H dry film gauge.

1. Advantages of dry film gauge

(1) Dual-purpose iron-aluminum probe 

This dry film gauge is suitable for the detection of the iron car surface paint thickness and the detection of the aluminum car surface paint thickness, which can quickly and automatically converted between different substrates. And it can also identify non-metallic substrates.

(2) No multi-point calibration

In addition to zero calibration, most dry film gauges also need to be calibrated with standard films. To measure the thickness of a certain range, it needs to be adjusted with a standard film of a certain range. The main reason is that it cannot meet the linear accuracy in the full range. Not only is the operation cumbersome, but also the roughness of the standard film surface.

(3) Temperature compensation

The measurement of the coating layer thickness is greatly affected by temperature. Measurement of the same workpiece at different temperatures will result in large errors. Therefore, a high quality dry film gauge should have ideal temperature compensation technology to ensure the stability of the sensor signal.

(4) Ruby wear-resistant probe

The wear resistance of the probe directly affects the measurement accuracy. We use a ruby probe with strong corrosion resistance and wear resistance to ensure the long-term effective use of the instrument. 

(5) Ultra-low power consumption

Coupled with the 3-minute no-operation automatic shutdown design, there is no need to frequently replace the battery, high efficiency and energy saving.

2. Dry film gauge application

Electroplating, spraying, pipeline anti-corrosion, aluminum profiles, steel structure. Dry film gauges are widely used in these industries.
