Optimal for sludge recovery of grinding coolant! "FINE MAG/K Type"

The magnet drum is different! Even if the magnetic force is increased, if the drum surface gets scratched, sludge cannot be scraped off. To maintain stable performance even after long-term use, we apply a special hardening treatment to the surface of the magnet drum, preventing scratches (patent obtained). ◆ The dewatering roller is different! - It consistently demonstrates stable dewatering without slipping. ◆ The cleanliness is different! - The magnetic force on the drum surface is 16% higher compared to our conventional products. - Stable product quality and reduced tank cleaning frequency. 〇 Regarding the collection of sludge from "grinding processing" coolant, please also take a look at the three case studies of "problem-solving examples (Company A / Company I / Company N)." ★ For more details, please refer to the "Product Catalog"! ☆ In collaboration with the manufacturer, we can provide proposals based on usage conditions and installation environments.

Unlike conventional ultrasonic thickness gauges (UT), there is no need to apply a couplant; thickness measurements can be taken simply by placing the probe on the measurement target, making it ideal for beginners and screening in large-scale sites. It can measure materials with paint, scale, thick linings, and slight surface roughness, significantly reducing the hassle of pre-treatment. Additionally, it is equipped with WiFi communication capabilities, allowing for the confirmation and management of measurement data and waveforms in conjunction with smartphones and tablets. This facilitates smooth sharing of measurement results and data management on-site. It is optimal for measuring wall thickness and conducting corrosion inspections of plant equipment, piping, tanks, and steel structures. It contributes to the efficiency and reliability of thickness measurements in the field of non-destructive testing (NDT), such as maintenance inspections and equipment diagnostics.

NDT Mart & Rental Co., Ltd. began sales of its new dual thickness gauge, the 'CT3500', on January 28, 2026. ◆ Dual Thickness Gauge 'CT3500' The 'CT3500' is a portable thickness gauge that supports a wide range of coating measurements from thin films to thick films. It employs a dual measurement method using electromagnetic and eddy current techniques, allowing for automatic differentiation between ferrous and non-ferrous substrates to measure coating thickness. The measurement range accommodates up to 3,500μm, making it suitable for measuring coatings from general painting to heavy anti-corrosion coatings and linings. With a measurement speed of approximately 0.2 seconds, it allows for efficient measurements even in inspection tasks that require multiple points. It is not only compact and easy to carry, but its display features an inclined design that is easy to see from both above and the front. Additionally, the upside-down display and background color (white/black) switching enhance visibility in dark, narrow, and outdoor environments, making it suitable for quality control within factories as well as for equipment inspections and painting checks in outdoor settings. It can be utilized for a wide range of applications, including painting management of bridges and steel structures, anti-corrosion coating measurements for pipes and tanks, and quality control in manufacturing sites. The 'CT3500' is a high-performance portable thickness gauge that provides stable measurements from thin to thick films, designed for field use.
