Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Features of the HT Unit: The actual frequency is displayed on a built-in digital counter. Land Use and Development.
Our large selection of inventory lets us fill your order immediately and at a completion rate that is extremely high in our industry.
Click to View the GrindoSonic Brochure. Resonant frequency can be determined by watching the voltmeter reach its highest point.
C Rapid Freeze-Thaw Apparatus.
Proof of claim is required. Remember me for one month. The Geotest Sonometer is the only system using a phono type cartridge as a pickup.
GrindoSonic HT System – HT-SYSTEM – Penn Tool Co., Inc
Complete refund or credit will be issued for unused and unmarked items returned within 10 days of receipt. To us, complete customer satisfaction means: It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Ease of use measurement system Connection to an High Temperature oven is possible Trigger level adjustable Option: Geotest Instrument Corporation S. Geotest Catalog Request Catalog.
Different computed values for the dynamic modulus of elasticity may result from widely different resonant frequencies of specimens of different sizes and shapes of the same concrete. Nails, Spikes, and Staples.
Changing accelerometer positions on the test specimen is time consuming. The oscilloscope confirms that peak reading on meter is actual resonance and not a harmonic.
Resonance Test Gauge
The test method may also be used to monitor the development of dynamic elastic modulus with increasing maturity of test specimens. Process control Number of programs 5 with controller unit B standard Grindosonic Number of Elevated segments 4 ast, B standard Grindosonic Optional: Other systems offer an oscilloscope connection.

ASTM C215 – 14
Click to see GrindoSonic Accessories. Click to order the GrindoSonic MK7 separately. The difference depends, in part, on the strength level of the concrete. ast
F Standard Specification for Driven Fasteners: Our extensive inventory is yet another way to keep you satisfied. Therefore, it is not advisable to compare results from specimens of different sizes or shapes. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. 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 C The oscilloscope verifies resonance because the meter alone also reaches high points on harmonics.
Product knowledge and commitment to customer service guarantees that your order is processed the same day you place it. The original PCA xstm has been modified by changing to solid state circuitry and addition of a built-in cathode ray oscilloscope.
