The Starr CTR-1000i digital coating thickness gauge suits users that require a dry film thickness gauge, (also known as DFT gauge) that can measure a coating on a metallic substrate that is either ferrous or non ferrous. The CTR-1000i has an integrated sensor, making it possible for single-handed testing. The backlit LCD screen displays the result, the minimum, maximum and average results. A set of 5 reference films as well as a steel and aluminium plate for zero calibration. It is commonly used in the automotive industry to measure the coating thickness of paint on steel and aluminium panels. Other uses include measuring the thickness of other coatings such as: Anodising on aluminium Galvanising on steel Chrome on hydraulic cylinder and rods Powder coating Intumescent fire resistive coatings The reason for measuring thickness is for maintaining quality assurance and cost control. If a coating is too thick, extra money is spent on the coating material. If a coating is too thin, it is not providing the protection it should, which can leave the product exposed to the possibility of damage. * Please note this gauge is NOT suitable for testing epoxy waterproofing membranes.
