Digimatic RTJ Ring Groove Caliper The Digimatic RTJ Ring Groove Caliper is a specialized digital measuring instrument designed for accurate measurement of Ring Type Joint (RTJ) grooves in valve flanges, pipe flanges, pressure vessel flanges, and high-pressure sealing applications. It enables precise inspection of both the inside and outside diameters of RTJ ring grooves, ensuring compliance with industrial sealing standards and flange specifications. Equipped with an ABSOLUTE measurement system, the caliper maintains the origin position even after power cycling, allowing fast and reliable measurements without repeated zero setting. Manufactured from high-quality stainless steel, it offers excellent durability, corrosion resistance, and long-term performance in industrial environments. The Digimatic RTJ Ring Groove Caliper is widely used in oil & gas industries, petrochemical plants, power generation facilities, pipeline manufacturing, valve production, flange machining, and quality control laboratories.
