Digital Concrete Test Hammer

Features
The host and sensor integration design is easy to operate and efficient. High-resolution LCD color screen 176*220 The power source is 4 pcs of AA alkaline batteries) Non-contact metal reflection grating + reflective encoder sensing, high accuracy Voice reported, LCD, and scale readings triple guarantee the accuracy of the data. Fieldwork without electricity and still can get the measured results through using the scale readings. Voice reported can improve the efficiency of work in a special environment. (Peer products in the market have no voice and ruler functions.) Using a USB communication interface, then quickly export the computer component data. Easy to operate, the software set the upper and lower rebound values, and the outliers can be automatically removed. Test hammer using imported parts, mechanical parts machining high precision, long service life. Superior price than the market peer-products.
