Kecepatan ultrasonik adalah parameter dasar untuk evaluasi tidak rusak pohon, bibit, kayu, veneer, produk panel kayu dan beton. Lokalisasi yang cacat dan penentuan sifat material dimungkinkan dengan mengukur kecepatan ultrasonik. Peralatan ini dirancang untuk uji veneer dan pembibitan.
usage instructions
- Connect the two pieso-electric transducers’ cables to the “probes” connectors of the timer.
- Couple the transducer to the sample. Poor coupling results in poor or incorrect result.
- Switch on the timer. Transit time in μs appears on the screen. The first readout after switch on is “0000”. This is normal.
- Please check 2-3 readouts. If the deviation between the readouts is not more than 1 μs, accept the data. Record the readout and change sample.
