Process control Number of programs 5 with controller unit B standard Grindosonic Number of Elevated segments 4 with Ashm standard Grindosonic Optional: Other systems offer an oscilloscope connection.
Resonance Test Gauge
The difference depends, in part, on the strength level of the concrete. Features of the MK7 Unit: Remember me for one month.
To us, complete customer aetm means:. This allows for greater flexibility in testing. The oscilloscope verifies resonance because the meter alone also reaches high points on harmonics. No items in cart. 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.
No other units of measurement are included in this standard. E Terminology for Nondestructive Examinations. Electrical power is converted by the driver into mechanical vibrations and these vibrations are imparted to the specimen under test. Resonant frequency can be determined by watching the voltmeter reach its highest point.

Our large selection of inventory lets us fill your order immediately and at a completion rate that is extremely high in our industry. Are you sure you want to empty the cart? Our customer service representatives are fully trained. The chassis measures 17x14x11″.
Ultrasonic E-Meter MKII
Referenced Documents purchase separately The documents listed below are referenced within the c15 standard but are not provided as part of the standard. Land Use and Development. Metals and Alloys Ceramics and more Geotest Catalog Request Catalog.
The actual frequency is displayed on a built-in digital counter. 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.
ASTM C, C The Geotest Sonometer is one of several devices now c2215 offered for determining changes in resonant frequency of concrete specimens subjected to alternate cycles of freezing and thawing with C Freeze-Thaw Apparatus. To us, complete customer satisfaction means: Click to order the GrindoSonic MK7 separately. All other units use accelerometers which require intimate contact with the test specimen.
Significance and Use This test method is intended primarily for detecting significant changes in the dynamic modulus of cc215 of laboratory or field test specimens that are undergoing exposure to weathering or aastm types of potentially deteriorating influences.
C Rapid Freeze-Thaw Apparatus. The apparatus consists essentially of a driver and pickup circuit. No other resonant frequency system includes an oscilloscope despite being strongly recommended in ASTM C paragraph 4. Click here to download full list of books. 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.
