MIT STRIKE 225-1 — digital rebound hammer for non-destructive testing concrete strength by the elastic rebound method. Designed for rapid determination concrete strength directly on construction site or when technical building inspection and structures.
Built-in threeaxis gyroscope automatically compensates the tilt angle when during tests — this key difference from base model STRIKE 225. Impact energy 2,207 J complies with international standardat hammers of type N.
Results are displayed on on colour 2,8-inch display. Memory — to 1000 test series and 100 000 impacts. Data transfer via USB and Bluetooth in application M-IT. Battery 3200 mAh — up to 3 days work.
The standard kit includes everything needed for immediate startup.
