ZC3-B wireless Bluetooth digital rebound meter

product description

This instrument is suitable for non-damage detection of C10-C60 concrete compressive strength in structural engineering. The data processing software has a built-in national standard "Technical Regulations for Testing Compressive Strength of Concrete by Rebound Method" JGJ / T23-2011 and some provinces, departments, cities, districts Local strength curve, the instrument conforms to the National Metrological Verification Regulation of the People's Republic of China "Rebound Instrument" (JJG817-2011), the sensor uses a non-contact grating optical chirp displacement sensor, no friction and no contact, so it has a longer service life and high stability
