GFV Associates, Inc. serves the vacuum process industry and the scientific community by supplying i services for measurement of vacuum. Our measurements are traceable to the National Institute of Standards and Technology (NIST) meeting the requirements of ISO 9001 standards and military specifications. · GFV Associates provides NIST- traceable calibration of your existing vacuum measurement equipment, usually a control and the tube used with the control. We also calibrate your existing tubes, providing a sensitivity (gauge factor) measured under standard conditions. For a description of our calibration services, click on CALIBRATE. · GFV Associates provides a complete line of hot-cathode ion tubes for vacuum measurement; these tubes may be used with our own control or controls manufactured by others. The tubes can be calibrated traceable to NIST. For a complete description, click on TUBES. · GFV Associates provides extensive consulting services for vacuum measurement. For a description of some of some past projects and our current capability, click on CONSULTING. System
Calibration Service
We will calibrate any control/tube combination, including hot cathode gauges, cold cathode gauges, and low-vacuum gauges against our National Institute of Standards and Technology (NIST) standards, providing a multipoint readout and graph, in the range from 10 -7 to 10 3 Torr. The service sets all of the available control parameters for the most accurate pressure readings, as well as establishing the functional performance of the system to a NIST-traceable standard. Hot-Cathode
Control Qualification Service
Ideally hot-cathode ion tubes could be calibrated and characterized by their sensitivity -- that is their "gauge factor" -- without regard to the control used to operate the tube. GFV calibrates tubes using our NIST-tested controls; the gauge factors so measured can be used to establish NIST-traceable pressure measurements when the tubes are used on other "qualified" controls. Hot-Cathode
Tube Calibration Service
Hot-cathode tubes from any manufacturer with any service history can be certified for use with GFV controls or qualified controls to provide NIST-traceable measurement with the same precision as new GFV tubes. Repair and Certification GFV continues to provide repair and certification for our IGC-1 and IGC-10 ionization gauge controls. Certification price is $250.00; delivery is one week from receipt of the control. Questions
and Answers About GFV's Calibration Service
Question: Why calibrate my high vacuum pressure-measuring systems? Answer: Because measuring equipment sensitivity changes. For example, using a pressure-measuring system, a process is determined to require a pressure reading of 1x10 -5 Torr or less. The lower curve of the figure shows the pumpdown curve for this process; in 30 minutes the system reaches a low enough pressure and the process is initiated. After a year, the pumpdown curve shown in the upper curve of the figure is observed; now it takes 46 minutes to reach 1x10 -5 Torr. The pressure-measuring system has drifted from its calibration at the time the process requirement was established. It is misinforming the operator; the system is really reaching the required pressure in 30 minutes and the operator is taking 16 minutes longer than necessary.
