Bot BOTE produced digital integrated Concrete Test Hammer RCL-2 Technical features: one-piece design, the Hammer and Hammer host combined organic sensors, without any cables, easy to carry. Using OLED display, 128x64 resolution, English switch interface, easy operation. Hammer uses non-contact optical sensor, completely avoiding the use of a potentiometer or by other contact sampling prone mechanical wear, poor contact and other defects, and a high precision, long life and other features, while retaining the mechanical pointer scale . Large-capacity data storage, can store up to 200 standard components, a standard component can detect up to 99 test area, fully meet the needs of the actual test work. Using USB communication port and U disk into a virtual way, no need to install any drivers, you can export the data to a computer. With real-time clock calendar function, can automatically detect the recording date and time of each member. Advanced low-power management function, you can set the screen backlight, automatic sleep, and automatic shutdown function, improve the use of the instrument time. 5, using high-power NiMH rechargeable batteries, long life, energy saving, long standby scope: site quality checks instruments applicable to government organizations metrology engineering quality testing, each engineering quality supervision agency, supervision units, on-site instant access The detection result is sampling the compressive strength of concrete structures, which greatly improves the efficiency of the various testing organizations to work quality. Application areas: real estate, highway bridges, testing organizations, supervision companies, and other concrete occasions.
