Supported Applications
The Omega DVG-64A is a digital vacuum gauge designed for measuring vacuum levels in HVAC systems and refrigeration applications. The device features a lifetime sensor resistant to contamination, making it suitable for environments where media purity or long-term stability is required.
Operating Conditions & Performance
The DVG-64A measures vacuum across two primary ranges: 0 - 19,000 Micron and 0 - 2,600 Pascal. Accuracy is specified as +/-10% or +/-10 Micron, whichever is larger, within the range of 50 to 2000 Microns at 75°F. The unit operates in ambient temperatures from 0°F to 150°F (-17°C to 65°C) and withstands an overpressure limit of 800 PSI max (55Bar). Response time is documented as 0.5 sec.
Display resolution varies by measurement range:
- Micron Ranges: 0 to 140 Microns offers 0.5 Micron resolution; ranges increase in steps up to 16,000 - 19,000 Microns with 1000 Micron resolution.
- Pascal Ranges: 0 to 18 Pascal offers 0.05 Pascal resolution; higher ranges step up to 2100 - 2600 Pascal with 100 Pascal resolution.
The gauge supports multiple units including Micron, milliBar, Pascal, Torr, and milliTorr.
Power & Display Features
- Power Source: 3 AA Batteries providing up to 600 hours of continuous usage with a battery indicator.
- Auto Shutoff: Activates after 10 minutes when vacuum reading is above 19,000 Microns; activates after 1 hour when below 19,000 Microns. A low power mode updates the display every 7 seconds if no button is pressed for 10 minutes while a vacuum is showing.
- Display: Backlit LCD with auto-shut off functionality and built-in hanger for convenient use.
Configuration Options
The DVG-64A series includes the following configurable or fixed attributes as documented in the user guide:
- Sensor Type: Thermistor-based lifetime sensor resistant to contamination.
- Process Connection: Standard ¼ inch male flare fitting.
- Housing Dimensions: 5.5" H X 2.75" W X 1.5" D with a weight of 6 oz.
Key Product Differences
The bundle documents the DVG-64A as a single model within this series. No alternative housings, sensor types, or output configurations are listed in the provided source material for other variants of the DVG-64A-Series.

1 Atm. to 1 mTorr with a mechanical gauge.
This meter works great in conjunction with a mechanical gauge. It starts working at 20 Torr, just before a mechanical gauge reaches zero. The combination gives a full range down to 1 mTorr. I wish there was a way to stop the auto shut off as the gauge goes through a calibration startup when I turn it back on. The instructions say nothing about the autocalibration. Does calibration work at vacuum? Don't know. A DC input from a external supply would solve this. (Or a comment in the instructions but instructions are hard. We need Monk's brother Ambrose Monk)

Can I Connect signal conditioner to get output on PC? OR How can I connect it to PC?
There is are no analog output or data communications capabilities on the DVG-64A.

Does this unit come with calibration? Is it NIST traceable?
Thank you for you inquiry
This unit only has a certificate of conformity that is available

I want to create vacuum at pressure level of 0.5 Pa absolute. Can I measure that pressure with this device?
This unit will not work for your application. This unit is a gage pressure reference device. It's accuracy is also +/-10% of full scale range which works out to a possible error of +/- 10 kilopascals
