Product Description


The Model 801W is a panel mount vacuum gauge with large text digital displays.

Ideal option to replace the discontinued Varian 801 pointer meter gauge.

The gauge is highly resistant to shock because it has no moving parts, thus requiring infrequent calibration.

This product is our best selling panel mount gauge, and the industry’s best value for a rugged vacuum gauge for measuring through 6 decades of wide range rough vacuum with optional SPDT controls.

The Model 801W features:

  • Panel mount design
  • Compatibility with Varian 531 sensors.
