  • Controls pump operation to maintain a preset vacuum level (to 800 torr) in a remote vacuum chamber
  • Especially important in testing or processing applications that require sustained exposure to a precisely regulated vacuum level
  • Extends the service life of your vacuum pump by allowing continuous operation
  • Repeated starts and stops, especially under existing vacuum pressure, can lead to back streaming of pump oil into the vacuum line, resulting in contamination and premature pump failure
  • Eliminates this problem by switching an optional solenoid vacuum valve on and off, which in turn controls vacuum pressure in the processing chamber
  • Includes a 3-digit LED display mounted in a 304 stainless steel housing, high and low vacuum control relays, and a piezo resistive vacuum tube (price includes mounting of sensor tube in a Terra vacuum chamber)
  • Order the vacuum solenoid for isolation of the vacuum pump from the processing chamber
  • Dimensions: 12" W x 11.25" D x 7" H
  • Weight: 16 pounds
  • Range: 0 - 800 Torr
  • Resolution: 1 Torr
  • Automatically controls pump operation to maintain stable vacuum levels inside a vacuum chamber
  • Includes easy-to-read digital vacuum gauge and piezo resistive pressure sensor for outstanding accuracy, stability and repeatability
  • Enhances pump life and efficiency
