HT-450KC Digital High Strength Rebound Tester

HT-450KC Digital High Strength Rebound Tester Application Industry

Used for the compressive strength of concrete components in high-rise buildings and bridges in structural engineering, usually suitable for concrete structures or components with a strength of 50-90MPa.

Features

Built in Bluetooth chip, can connect to mobile app to upload rebound data in real time;

Optional Bluetooth printer, on-site printing of original records and test results

2.8-inch touch LCD screen, diversified input methods, simple interface, easy to operate

Support remote upgrades, synchronize industry standard updates with curves, and can be customized exclusively for users;

One on one analysis software for PC, easy to process data result analysis and generate detection reports

Built in GPRS, supports data cloud upload. The instrument transmission account is built-in at the factory and can be used immediately upon startup

During special working condition detection without mobile phone signal, after normal detection is completed, it will automatically upload when turned on within the coverage range of the mobile phone signal
