RD-ML Concrete Dynamic Modulus Tester Introduction: For a certain object, there exists an inherent resonant frequency. When the volume or material of an object is constant, its resonant frequency is only related to its density. Therefore, the natural vibration frequency of an object determines its strength. If the resonant frequency of the object can be measured, the strength of the object can be calculated based on strength theory. A motion sensor is an instrument that uses the above principles to measure the resonant frequency of an object. It can be widely used in metallurgy, construction, bridges, hydropower and other fields for measuring the elastic modulus of concrete, carbon, slate, glass, brick, plastic and metal materials. The application fields of concrete dynamic modulus tester include colleges, research institutions, testing units, as well as metallurgy, construction, bridges, hydropower and other fields characteristic: 1. The manual measurement frequency sensitivity has reached 1Hz, and frequency hopping scanning can be performed from 100HZ to 20KHZ (i.e. coarse scanning with ten, hundred, thousand, or ten thousand bits), and fine scanning (fine scanning with more accurate digits after reaching the value, until accurate to 1HZ). 2. Comes with memory: can store 100 test data, export data for centralized printing, etc. 3. Full Chinese LCD display: Real time display of current scanning frequency, resonance peak frequency, and signal strength. Compared with other manufacturers' oscilloscope displays, it has the advantages of intuitiveness, high accuracy, and easy reading Technical parameters: Frequency measurement range: 100Hz~20kHz Measurement error<2% Frequency sensitivity: 1Hz Output power: 0-15W Output method: ① Full Chinese LCD display ② Thermal printer printing ③ Equipped with dedicated interfaces and analysis software for computer communication (optional for users) Environmental conditions: 0-50 ℃, relative humidity<80% Power supply: AC220V, 50Hz,<60w Working hours: Can work continuously for 8 hours
