·Multi probe and multi-point measurement meet the requirements of complex coating structures: CurveX 4 supports configuring different types of probes (magnetic, clamp, ring, line) to adapt to different measurement points. This means that synchronous monitoring can be carried out on the surface of the steel plate, the air layer inside the drying chamber, or the back of the coating to comprehensively grasp the temperature distribution and curing status
Why are these applicationsImportant in the steel/color coating industry
In the steel and color coating industry,coating thicknessDirectly affecting the anti-corrosion performance, service life, and appearance quality of the product. Thin coating may result in weak weather resistance, while thick coating may waste materials or affect adhesion. Under the umbrella of Industrial PhysicsSpecMetrix optical interference non-contact precision thickness measurementTechnology provides reliable data support.

Corrosion test and salt spray cycleIt is a standard method for evaluating the durability of steel and protective coatings. An efficient and reliable test chamber can help companies reduce repair rates and improve product stability.
Furnace temperature trackingIt is crucial in processes such as heat treatment, galvanizing, coating, and baking; Temperature deviation can affect coating adhesion, surface properties, and structural properties. High precision trackers can provide key data for process optimization.
