万喜堂app下载老虎机 thyrcont图拉特真空计VSM79D 
The digital combination transducer VSM (Pirani / cold cathode) measures absolute pressure from atmospheric pressure to ultrahigh vacuum.
Microcontroller intelligence automatically manages the optional interplay of both vacuum sensors.
Smartline represents cutting edge technology providing safe, precise and cost effective process control.
