zstm Search book title Enter keywords for book title search. To us, complete customer satisfaction means:. Look through our website. The conditions of manufacture, the moisture content, and other characteristics of the test specimens see section on Test Specimens materially influence the results obtained. The actual frequency is displayed on a built-in digital counter. This apparatus closely follows design parameters set up over 40 years ago by the Portland Cement Association research laboratories.
The chassis measures 17x14x11″. See 4 more pictures.
Resonant frequency can be determined by watching the voltmeter reach its highest point. Advanced Search Search Tips. 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. The test method may also be used to monitor the development of dynamic elastic modulus with increasing maturity of test specimens.
Features of the MK7 Unit: Please login to your authorized staff account to use this feature. Remember me for one month.
E Terminology for Nondestructive Examinations. Therefore, it is not advisable to compare results from specimens of different sizes or shapes.
When resonance occurs, the actual number is digitally displayed on the frequency counter. Electrical power is converted by the driver into mechanical vibrations and these vibrations are imparted to the specimen under test.

Complete refund or credit will be issued for unused and unmarked items returned within 10 awtm of receipt. All other units use accelerometers which require intimate contact with the test specimen. Our large selection of inventory lets us fill your order immediately and at a completion rate that is extremely high in our industry.

If you like to setup a quick demo, let us know at support madcad. The difference depends, in part, on the strength level of the concrete. Geotest Catalog Request Catalog.
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. Significance and Use This test method is intended primarily for detecting significant changes in the dynamic modulus of elasticity of laboratory or field test specimens that are undergoing exposure to weathering or other types of potentially deteriorating influences.
Other systems offer an oscilloscope connection. Changing accelerometer positions on the test specimen is time consuming.
