Tim Collins (President) Introduces the DigiVac company. Tom Bassi demonstrates the calibration process for vacuum gauges.

Every vacuum gauge manufactured by DigiVac is calibrated against NIST standards to ensure accuracy. Using 3 vacuum pumps (rotary driven oil based pump, rough vacuum oil based pump, high vacuum diffusion pump. 10 ports to test vacuum gauges. Tom Bassi states, “Calibration is taking an instruments readings of known or correct magnitude and applying them to another instrument of which we are unsure of the readings.” Vacuum gauges of different sensitivities are used depending on the vacuum instrument being tested.

What you will learn:
- Learn how vacuum gauges are calibrated
- Describe the process and instrumentation required to calibrate instruments
- Appreciate the importance of NIST calibration

Featuring:
Model 200 Pirani, Model 801W
