Liberty Steel has recently purchased a 72″ ProEco slitter from Worthington Industries with one of our AGT400 gauges included. Liberty Steel has purchased a replacement source for the AGT400 Isotope Gauge, and will be installing it between March and April of next year.

Due to the durability and long lifespan of our AGT400 Isotope Thickness Gauge, buying our used gauges is a cost-effective, low-risk solution for companies interested in our gauges. The AGT400 has spent decades building its reputation as the most dependable thickness gauge in the industry. On top of the discounted price of a used gauge, companies like Liberty Steel Products will enjoy lifetime service from our own AGT technicians. With both a dependable gauge and reliable service, buying used is another way to keep your facility efficient and speedy.

As the seasons shift, so do the physical properties of many raw materials and that can wreak havoc on process consistency. High summer humidity can increase the moisture content of raw inputs like iron ore, sinter, coke, or even added materials like plastic polymers used in injection processes or composite production. In winter, extreme cold can cause materials to contract or become brittle, affecting volume, weight, and handling. These fluctuations make accurate, real-time measurement critical to maintaining efficiency, product quality, and safety throughout the year.

That’s where laser and isotope gauges shine. Unlike traditional mechanical or contact-based systems, these non-contact measurement solutions aren’t affected by buildup, condensation, or temperature swings. Laser gauges offer precise distance and thickness readings in nearly all environments with proper care, while isotope gauges deliver consistent level measurements regardless of material state or ambient conditions. Rugged and reliable, they’re built to perform in the heat of summer or the dead of winter, giving you year-round confidence in your process control.

In honor of Labor Day earlier this week. We’re proud to support the American steel industry with precision gauging technology that keeps production efficient, accurate, and safe. From isotope thickness gauges to cutting-edge laser measurement systems, our products are designed, engineered, and built right here in the USA; because we believe American manufacturing deserves American-made tools.

Windows 10 and older versions are no longer receiving updates or security patches from Microsoft. This makes your current system slower, less secure, and increasingly incompatible with new software. Now’s the perfect time to upgrade to a brand-new computer with Windows 11: built for speed, security, and modern performance. Our latest systems come ready to go, and we’ll even help you transfer your data. Don’t wait until problems arise. Upgrade today for a smoother and safer experience!

Advanced Gauging Technologies is proud to announce a new purchase order from Nucor Steel California (CSI) in Fontana, CA for two state-of-the-art AGT400 Isotope Thickness Gauges. These gauges will be installed on the No. 3 Continuous Galvanizing Line (CGL), with shipment scheduled for August 2026.

Purpose-built for the metals industry, the AGT400 delivers fast, accurate, and reliable non-contact thickness measurements that help optimize production and ensure consistent quality. By integrating the AGT400 into their CGL line, Nucor CSI is reinforcing its commitment to high-performance process control, superior product quality, and efficient operations.
