DH-100 Portable Metal Hardness Tester by Time Instruments


Time Instruments' DHT-100 Portable Hardness Tester is an advanced Leeb’s-type hand-held Digital Metal Hardness Tester with high accuracy, wide measuring range, and easy operation. It is suitable for testing the hardness of all metals and is especially useful for on-site testing of large structures or assembled components. Leeb’s-type rebound hardness testers are widely used in manufacturing plants, testing laboratories, and engineering companies.

DHT-100 can be used on the desk-top or lab table, or strap the meter to the wrist to enable testing of any parts in any location or position. Large LCD display of hardness values in hardness scales: Leeb, Rockwell C or B, Brinell, Vickers, and Shore, as well as average, minimum, maximum, and mean values, with back light for use in darker environments. Tester will alarm when hardness values exceed user-set limits. Optional data storage with RS232 serial download cable.
