HT225-V Digital Concrete Test Hammer For Testing The Rebound Strength
HT225-V Digital Voice Test Hammer
Application:
It is used to test the compressive strength of building concrete components, bridge and so on. It is designed specifically for the non-destructive testing of hardened concrete structures. The instrument is used for quality Inspection Company, site testing or sampling and laboratory center.
Standard:
GB/T 9138-1988 Concrete test hammer
BS EN 12504-2:2001 Testing concrete in structures-Part 2: Non-destructive testing – Determination of rebound number
ASTM C805/C805M-2008 Standard Test Method for Rebound Number of Hardened Concrete
BS 1881 Testing concrete Part 202 Recommendations for surface hardness testing by rebound hammer
JJG 817-93 Concrete test hammer
JGJ/T23-2011 Technical specification for inspecting of concrete compressive strength by rebound method

Features:
1. Equipped with infrared portable printer, can print test report on site.
2. The software can set rebound value from upper limit to lower limit, and the abnormal date will be deleted automatically.
3. USB interface, easy to connect with PC
4. Born with voice service, color screen display and traditional scale, more accurate, in case power off when site work, we still can make use of the scale to continue work. Voice service can make your work efficient.
5. No-touch metal reflect grating and reflect compile sensor, better accuracy.
6. Large capacity rechargeable lithium battery, economic and environment protection, long use life
7. LCD color screen 176*220 (other manufacturers’ are black and white, low resolution)
8. Combined with displayer part, easy to operate and make your work efficient
