HT-225V Digital Concrete Schmidt Hammer (Main Parts made in Japan)            
Test hammer HT225-V submitted to GB /T9138-1988, JJG817-93 and JGJ/T23-2001 standards. The instrument is useful for quality Inspection Company, site testing or sampling and laboratory center, don’t have to manual calculation, machine automatically compute, grade and printing.
1). The test hammer is combined with displayer part, easy to operate and make your work efficient.
2). LCD color screen 176*220 (other manufacturers’ are black and white, low resolution)
3). Large capacity rechargeable lithium battery, economic and environment protection, long use life, better than other market product (one time use battery)
4). No-touch metal reflect grating and reflect compile sensor, better accuracy. (other manufacturer’s are ordinary transmission grating and optical coupler, or carbon film and brush touch sensor)
5). 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. (similar product of other manufacturers’ in market no voice service and scale)
6). USB interface, easy to connect with PC
7). The software can set rebound value from upper limit to lower limit, and the abnormal date will be deleted automatically.
8). Equipped with infrared portable printer, on site print test report.
