  • Wide range power supply 100 - 240 V
  • Unit of pressure selectable between mbar, Torr and Pascal
  • Compact, rugged Penning (CPG) sensor insensitive to operation at high pressures
  • Aligned and temperature compensated Pirani (PRG) sensors
  • Cost-effective replacement sensors and electrodes
  • Erro message for each channel, for example in the case of broken filament, defective sensor line or failed plasma discharge
