Defective items will be either replaced or repaired. Frequency analysis FFT calculation for detections of multiple vibrations modes Selection of zones of asm by waveband filtering Oscilloscoop function for time domain analysis Graphic visualisation of frequency domain Technical Information: Different computed values asm the dynamic modulus of elasticity may result from widely different resonant frequencies of specimens of different sizes and shapes of the same concrete. Print 1 2 3 4 5 page sstarting from page current page.

No other units of measurement are included in this standard.

The apparatus consists essentially of a driver and pickup circuit. Our extensive inventory is yet another way to keep you satisfied.

Product Information

No other resonant frequency system includes an oscilloscope despite c2215 strongly recommended in ASTM C paragraph 4. This apparatus closely follows design parameters set up over v215 years ago by the Portland Cement Association research laboratories.

Other systems offer an oscilloscope connection. This item is part of the following categories: Product knowledge and commitment to customer service guarantees that your order is processed the same day you place it. The Geotest Sonometer is the only system using a phono type cartridge as a pickup. The value of the dynamic modulus of elasticity obtained by this test method will, in general, be greater than the static modulus of elasticity obtained by using Test Method Cc215 With the Geotest pickup and driver mounted on portable stands, 2c15 is not necessary to use a test bench, which is mandatory on other apparatus.

The chassis measures 17x14x11″.

Changing accelerometer positions on the test specimen is time consuming. ASTM C, C The Geotest Sonometer is one of several devices now being offered for determining changes in resonant frequency of concrete specimens subjected to alternate cycles of freezing and thawing with C Freeze-Thaw Apparatus.
