HT-225DS

The HT-225DS Digital Rebound Hammer is an advanced solution for non-destructive testing (NDT) of concrete compressive strength, combining precision engineering with smart digital technology. This innovative device features a unique modular design that separates the mechanical hammer body from the digital processor, allowing for quick field replacement of components when needed. It mainly includes 1 digital/mechanical rebound hammer unit, 1 high-capacity lithium-ion battery and charger, 1 Mini-USB data cable, 1 calibration anvil, and 1 product manual.

Features
· Built-in large capacity memory stores up to 1000 components with 16 test zones and 16 test points each· Built in large capacity rechargeable lithium ion battery, long service life of the test hammer
· Supports both standard measurement mode and customizable testing modes· Support break-point continuous test, and data collection is more convenient and humanized
· Automatic correction for test angles, casting surfaces and carbonation depth up to 6mm· Support Bluetooth online, expand the use of mobile app connection, and make it more convenient to upload data to the cloud with the cloud server
· Features non-contact optical sensor technology for wear-free operation and longer service life
· Support system upgrade. According to user feedback, the company will upgrade the system regularly to improve the use experienc
