I. LS223 Coating Thickness Gauge Introduction
Linshang LS223 coating thickness gauge also called coating thickness tester is an instrument that separates the host from the probe. The measuring range is 5000μm and the meter can automatically identify the measuring substrate. This instrument uses both Hall Effect and eddy current measurement principles to measure the non-magnetic coating thickness on magnetic substrates and the non-conductive coating thickness on non-magnetic substrates. It is a dual-use instrument for both ferrous and non-ferrous substrates.
II. LS223 Coating Thickness Gauge Application
LS223 coating thickness tester is widely used in hardware manufacturing, shipbuilding, aerospace, mechanical equipment evaluation and other fields. This meter is especially suitable for large thickness coating inspection. The following are a few examples of practical applications of the LS223 coating thickness gauge for reference. (The following measurement industries do not represent all)

IV. LS223 Coating Thickness Gauge Characteristics
1. The probe supports trigger power-on, it can automatically identify the measurement substrate and automatically switch
2. No calibration is required, just simple zero adjustment for a new measurement.
3. The LS223 coating thickness tester has wide measurement range and the thickest measured materials can be 5mm.

4. Adopting advanced digital probe technology to provide good measurement accuracy and measurement repeatability to ensure the inspection of Chinese national metrology. The test data of Linshang LS223 coating thickness gauge can be compared with the test data of foreign coating thickness gauge.
5. The instrument has the temperature compensation function and digital function of the analog signal end, which can make the sensor signal of the coating thickness gauge more stable. The test accuracy of the instrument is not affected under the condition of large temperature changes.
6. The coating thickness meter has a real ruby probe, it has a strong resistance to corrosion and abrasion, which can extend the service life of the meter.
7. LS223 has three measurement modes: iron-based measurement (Fe), non-ferrous-based measurement (NFe) and automatic identification (Fe / NFe). Language (Chinese and English) and unit can be set.

8. This product can trigger the start-up, applicable to ultra-thin substrate: Fe: 0.2mm / NFe: 0.05mm.
