Easier Leak Detection
High-resolution digital readings make small vacuum changes easier to identify than estimating between analog dial markings.

VACUUM MEASUREMENT
What is a digital vacuum gauge?
A digital vacuum gauge measures pressure below the surrounding atmosphere and presents the reading as a numerical value. In vacuum bagging and resin infusion, it helps an operator observe vacuum level, check stability and record changes during a defined test.
The DVS-G displays vacuum in inches of mercury vacuum (inHgV). As the vacuum deepens, the displayed inHgV value increases. The reading describes conditions at the measurement point; gauge placement, restrictions and long hose runs can affect how well that point represents the bag.
When comparing digital vacuum gauges, match the measurement units, range, accuracy, connection and documentation to your process. The DVS-G is presented here for composite process monitoring; an inHgV reading should not be treated as a micron-scale absolute-pressure measurement.

INTERPRETING THE SPECIFICATIONS
Resolution, accuracy and the vacuum reference
0.1 inHgV display resolution
The display changes in tenths of an inch of mercury vacuum. Resolution is the visible increment; it is separate from the stated accuracy of ±0.075 inHg.
29.6 inHgV range/reference
The published DVS-G range is 0.0 to 29.6 inHgV, and the site uses 29.6 inHgV as a full-vacuum reference. Actual attainable readings depend on local atmospheric pressure, altitude and system conditions. This is not a universal acceptance target.
Confirm your process requirements
Discuss required accuracy conditions, verification or calibration documentation, connection compatibility and operating conditions when requesting a quote. Use the requirements in your controlling procedure to select the instrument.
INSTRUMENT SELECTION
Digital vs. analog vacuum gauges
Analog gauges show vacuum with a needle against a printed scale. A digital vacuum gauge presents a numerical reading, reducing the need to estimate between dial markings. That can help operators compare beginning and ending values during timed tests.
| Consideration | Digital | Analog |
|---|---|---|
| Reading | Numerical value; DVS-G has a high-visibility LED | Needle position on a graduated dial |
| Small changes | Visible as changes in the displayed increment | Depend on dial spacing, scale and viewing angle |
| Recording | Operators can manually record the displayed number | Operators estimate and record needle position |
| Selection | Match accuracy, range and verification requirements to the process; display technology alone does not establish suitability. | |
Digital monitoring does not improve the vacuum source by itself. Analog indication may be adequate for broad tolerances or a validated procedure. Read the full digital vs. analog comparison →
COMPOSITE PROCESS APPLICATIONS
From bag checks to leak troubleshooting
Vacuum bagging
Use a digital vacuum gauge for vacuum bagging to observe evacuation and stability at the selected measurement point. Place the gauge so the reading is meaningful for the bag and follow the approved process.
Resin infusion
A vacuum gauge for resin infusion supports pre-infusion bag checks and monitoring. Confirm vacuum integrity before introducing resin, using your process-defined acceptance criteria and measurement arrangement.
Vacuum drop testing
Evacuate, allow stabilization, isolate as required by the procedure, then record starting and ending values over the specified interval. The DVS-G helps make small displayed changes visible. Read the drop-test guide →
Leak troubleshooting
Use readings as feedback while checking bag seals, fittings, lines and connections. Vacuum drift can also reflect material outgassing, temperature or stabilization; a changing reading alone does not locate or prove a leak. Explore leak troubleshooting →
On larger parts, consider measurement location and multiple points where required. Review gauge placement guidance →
QUALITY & TRACEABILITY
Documentation that supports your purchasing requirements
DVS-G records can connect critical component serial numbers, final assembly verification and completed functional testing to the finished gauge. Discuss Certificate of Conformance, serial-number traceability and any calibration documentation requirements with DVS before ordering.
A Certificate of Conformance and final functional verification serve different purposes from calibration documentation. Confirm which records are available and suitable for your quality system; do not infer accredited calibration or a particular certification from traceability alone.
For aerospace, defense and other controlled manufacturing work, the customer’s drawing, specification, approved procedure and quality requirements govern instrument acceptance and use. Application descriptions do not establish approval for a specific aircraft, platform or program.
