Digital High Contrast Oled Display Concrete Test Hammer Automatic Calculating

HT-225D Integrated Rebound Hammer OLED Display with Software to PC

Introduction

HT225D Digital Rebound Apparatus has the following characteristics: integrated design, small in size; adopt non-contact optical coupler sense to realize data collection, without changing the original physical structure of mechanical rebound apparatus, in which way the optical coupler sensor has no contact nor friction with the mechanical part of rebound apparatus and thus its service life is extended; inside of the apparatus, national curve and local curve are provided, can be set optionally by yourself; angle, tested surface, pumping or not, carbonization depth and other parameters can be set on site; after detecting data of original value, the original rebound value, testing zone strength value, component overall strength value and other data of the completed component can be checked immediately; self-contained access control further reflects the fairness and safety of the test; equipped with USB data transmission interface, able to transfer data to computer; computer software saves the test data as Excel format, and reporting format can be created immediately, simple and convenient for the later software process; memory space of original data are as much as 1000 components.
