UltraSoundGate 116Hm (mobile)

part # 41165
# 41166
Very small sized mobile ultrasound recording interface with a balanced analog input, peak level meter, trigger button, acoustic monitoring output, rugged aluminium housing, USB 2.0 interface, recording software Avisoft-RECORDER USGH and water-proof transport case. Thanks to its small size and the integrated peak level meter, this unit is certainly suited for hand held use with small Ultra Mobile PCs (subnotebook or netbook) in the field.
