JK-AV-6256Ambient vibration analyzer
Introduction:
JK-AV-6256ambient vibration analyzer is a high intelligent pocket measuring instrument.It can measure W.B.z( also named environmental vibration level) , W.B.x-y and Lin.It can meet the requirements of ISO80412- human response vibration meter and GB/ 10071
128� 64 dot matrix LCD display, with background light, Chinese menu, abundant content, Chinese tips function, easy to operate.The measuring result can be stored in the analyzer for a long time, and can be print through the RS-232 interface by the micro printer or be send to a computer to be conducted.
