Dakota Japan Co., Ltd. (Headquarters: Saitama City, CEO: Yoshitomo Fukazawa), which specializes in the sale of various testing equipment such as ultrasonic testing devices and hardness testers, will begin selling its new portable Rockwell hardness tester, 'TKX LIGHT', starting June 25.
The 'TKX LIGHT' is a portable hardness tester that allows for easy and high-precision measurement of the hardness of metallic materials. It adopts the principle of the Rockwell hardness test and boasts excellent reproducibility of ±0.4 HRC, achieving stable hardness measurements. It is suitable for high-precision hardness measurements in both field and laboratory settings.
The testing subjects range from non-ferrous metals such as aluminum, copper, brass, and bronze to a wide variety of metallic materials and surface treatments, including hard and soft steel, hardened steel, nitrided products, carburized products, and chrome-plated surfaces. Measurement data can be stored up to 3,500 entries, and it supports tolerance setting, statistical data management such as maximum, minimum, and average values, as well as external output of measurement values via RS-232. Additionally, the minimum measurement thickness is 0.08mm (for 65 HRC), making it suitable for hardness measurement of thin plates and surface treatment layers.
