Description

 

 

 

The DHT-300 Plus Integrated Hardness Tester utilizes state-of-the-art micro-electronic technology. This uniquely designed pocket-size instrument comes with a pocket sized carrying case and incorporates a hardness impact probe, microprocessor and data display in a single, compact unit.

 

The main new features of DHT-300 Plus includes data display with statistic, impact direction automatic recognition (fully 360 deg), enlarged storage capacity with output and software, USB interface for both recharging and data transfer to your PC or printer, OLED display for use in dark areas, and much more.

 

The DHT-300 Plus conforms to ASTM A956 and provides exceptional reliability for a wide measuring range, and is capable of automatically converting and displaying measurements into Brinell, Rockwell, Leebs, Vickers and Shore hardness values.
