CUTE 102A is a portable apparatus for Non-Destructive evaluation of concrete quality by Ultrasonic Pulse Velocity (UPV) measurement method. It is used to measure the transmission time of ultrasonic pulses in the test specimen, from which the velocity can be computed. A set of UPV readings can be used for further interpretations of structural concrete. The equipment is designed to comply with the recommendations of BS 1881 (Parts 210 & 203), ASTM C 597-71 (Reapproved 1979) and IS-13311 (Part I); 1992.The Instrument generate pulse of ultrasonic frequency, which are coupled into the concrete specimen under test by the transmitting transducer. The receiving transducer is used to detect these pulses & to convert them back into electrical pulses. Suitable coupling media are used to minimize the losses due to acoustic mismatch at the transducer-specimen interfaces. A 10MHz Quartz time base ensures accurate measurement of pulse transit time (T) with a resolution of 0.1 microsecond. The path Length (L) can be measured with a tape & hence the Ultrasonic Pulse Velocity (UPV) in the specimen under test can be computed as, V = LT
