Concrete Digital Voice Rebound Hammer Resiliometers

Test hammer HT225-V confirm to GB /T9138-1988, JJG817-93 and JGJ/T23-2011 standards. The instrument is popularly used for quality Inspection Company making supervisory monitoring, random monitoring ,on-the-spot testing, and also used for sampling and laboratory center. No need to manual calculation. Machine automatically compute and show result.

Traits：

• 1. Designed by ROK International with completely independent intellectual property rights.
• 2 One-piece structure design; No need to connect any wiring; Convenient to carry; low breakdown rate.
• 3. The test hammer adopt to true color LCD display screen. (resolution ratio176*220). Easy to operate and make your work efficient.
• 4. The voice function let testing personnel not see the value and improve test efficiency.
• 5. Test hammer adopt to Non-contact metal reflection grating sensor avoiding physical deterioration and poor contact defect. It improves accuracy and use time. Meanwhile, maintain the mechanical pointer scale.  
• 6. External infrared transmission portable printers can make the test report on-the-spot right now.
• 7. Great capacity data storage. It can store the most 200 standard elements. One element can test 99 test areas completely meeting the need of the actual detection work.
• 8.The test hammer set Internal uniform curve. Customer can add up to 20 test curves.
• 9. Measuring area parameters can record on-the-spot and automatic compute component results.
• 10. The software can set rebound value from upper limit to lower limit, and the abnormal date will be deleted automatically
• 11. USB interface, easy to connect with PC. No need to install any drive program.
• 12. Calendar and clock function can automatic record each component testing date and time.
• 13. Advanced low power consumption power management function can install screen backlight, voice volume, auto Sleep, auto power shut off to improve battery life.
