Product Overview of Dynamic Elastic Modulus Measuring Instrument:
For a certain object, there exists an inherent resonant frequency. When the volume or material of the object remains constant, the resonant frequency of the object is only related to its density. Therefore, the inherent vibration frequency of the object determines its strength. If the resonant frequency of the object can be measured, the strength of the object can be calculated based on the strength theory. The dynamic measuring instrument is an instrument that measures the resonant frequency of an object using the above principle. It can be widely used in fields such as metallurgy, construction, bridges, hydropower, etc., for the measurement of the elastic modulus of concrete, carbon, slate, glass, brick, plastic and metal materials.
New features of the dynamic elastic modulus measurement instrument:
The STDT-12 elastic modulus tester has the following functions compared to other products:
1. The manual measurement frequency sensitivity reaches 1HZ. It can perform frequency sweeping from 100HZ to 20KHZ in steps (i.e., sweeping in the hundreds, thousands, or tens of thousands, or in rough steps), fine sweeping (fine sweeping to the value and then further fine sweeping in more precise digits until it is accurate to 1HZ).
2. Built-in memory: It can store 100 sets of test data. Data can be exported for centralized printing, etc.
3. Full Chinese LCD display: Real-time display of the current scanning frequency, resonance peak frequency, and signal strength. Compared with the oscilloscope displays of other manufacturers, it has the advantages of intuitive, high accuracy, and convenient reading.
New features:
Code switch, one-click operation: The ALPS code switch features a good operation feel and long service life. It has a one-click all-in-one operation function, combined with a full Chinese operation prompt menu, allowing you to easily control the equipment. It is simple, clear, and straightforward to understand. Thermal printer, economical and low-noise: This machine uses a new type of thermal printer, which is faster in paper output, has less noise, and has high printing quality. It operates stably. During use, only paper replacement is required without the need to change the carbon tape. At the same time, the software can be set to a paper-saving mode or for centralized printing. Major improvement of metal probe, elegant and attractive: The exterior adopts electroplating technology, giving it a shiny luster and a more dynamic appearance; the magnetic path and sound path design make the probe more sensitive and have good repeatability. At the same time, it has high impact resistance, making it sturdy and durable, achieving a better integration of visual perception and functionality.
