Tianjin of Huayin fine HT225W fully automatic the digital resiliometer 1. Usage * for rebound method to measure the compressive strength of concrete. 2. Features * full compliance with regulatory requirements, host screen and mechanical pointer resiliometer, simultaneously display rebound readings, at any time to check the consistency of the readings; * Easy to operate, the boot that is measured; * Field test point of view, the test surface, the pump send carbonization amended, and may show strength test results; * The host can be equipped with with multiple mechanical resiliometer, to ensure that the detection work continuously; * Data analysis software automatically generated test report. 3. According to the standard rebound method to detect concrete compressive strength of the technical specifications (JGJ/T23-2001) 4. Technical indicators * Strength Measurement range: 10 to 60MPa; * nominal kinetic energy: 2.207J; the * bomb hit a tension spring stiffness: 7.84N/cm; * showing the value of consistency error: ≤ ± 1; * Size: φ60 × 280mm, 190 × 150 × 50mm.
