The DHT-40 is a pen style hardness tester. It has premium integrated electronics packaged into an easily portable pocket sized case which includes the impact device. State-of-the-art technology gives extraordinarily high accuracy.
The DHT-40 uses the Leeb method to measure hardness of any metal or surface for a wide variety of industrial purposes. The Leeb method is noted for its accuracy, wide measuring range and operating simplicity.
The DHT-40 hardness pen conforms to the Standard ASTM A956 and comes with a USB cable and software for PC downloading of data. A rugged carrying case and test block are also included.
