The instrument gives data concerning the homogeneity of the concrete, by generating pulses of sound into the concrete and measuring the time the sound travels from the transmitter probe to the receiver probe through the material. Furthermore, it is possible to have indicative data on the strength of the concrete. Measuring range: 0 - 3000 µs - resolution ± 0.1 µs Selection of the ultrasonic pulse amplitude adjustable from 250 to 1000 V Measurement of the time required by the ultrasonic pulse to go through the tested material. Single or continuous acquisition mode with automatic or manual saving. Zero calibration with depuration of the time for the pulse to go through the probes. Battery duration: 6 to 8 hours. Capacity of data acquisition, processing and filing of the test data up to 30.000 samples. Interface mini USB for PC connection. Two outlets for connection to the oscilloscope. Languages: English, French, German, Spanish, Italian. The use of the instrument is made easy because it is based on a user-friendly system. The standard appliance includes: The instrument is in basic configuration in a practical palmer container. Two 55kHz probes with connection cables. Battery rechargeable pack NiMh 4.8V > 2000mA/h with low battery condition alarm. External feeder 230V and battery charger 12V 500mA. Case dimensions: 400x340x110mm
