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

This panel mount vacuum 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 (Model 801-W2C).

Every Model 801W is pre-tested and calibrated under actual vacuum against a NIST standard. Note: NIST certification included with the gauge is an available option to add to your order

Optional Features
