Supported Applications
The Omega DPG108 is a battery-powered digital pressure gauge designed for easy on-site installation. It utilizes a high-precision piezo-resistive pressure sensor with signal amplification and A/D conversion to display readings on an LCD. The series supports gasses and liquids compatible with stainless steel wetted materials.
Documented industries include hydropower, water, petroleum, chemical, mechanical, and hydraulic sectors. WARNING: These products are not designed for use in, and should not be used for, human applications.

- Accuracy: ±0.25% FS for gauge pressure >5psi; ±0.5% FS for all others including absolute, compound gauge, and Vacuum ranges.
- Stability: ≤0.1% FS per year
- Overload Pressure: 150%~200%
- Sampling Rate: 4 times per second (≤4 t/s response time)
- Resolution: 4 Digits
- Power Supply: 9VDC with efficient power usage exceeding 2,000 hours in power-saving mode.
Variants and Configurations
The series is available across multiple pressure ranges indicated by model suffixes (e.g., -005G, -1.0KG, -V100G). The standard process connection is 1/4 NPT.
- Pressure Types: G / A / D
- Engineering Units: psi, bar, kPa, MPa, kg/cm²
- Housing Material: Silicone case (IP65/IP68)
- Wetted Materials: SS316
- Dimensions: 35 mm diameter x 85 mm height x 4 mm depth
Configuration Options
The DPG108 features a high-resolution, back-lit LCD display that automatically records maximum pressure values during measurement. The unit includes an adjustable auto shut-off function ranging from 0 to 15 minutes.
- User Interface: Short press On/Off button for power; long press to change engineering units.
- Peak Pressure Reset: Short press "Zero" button.
- Clear Display: Long press "Zero" button.
The device includes a password-protected setting menu (default 1000) accessible by pressing the On/Off and Zero buttons simultaneously. Menu options include lock, auto-off time (offt), back light time (blt), and exit settings (end).
Key Product Differences
The DPG108 series encompasses 22 enabled variants covering gauge pressure, absolute pressure, compound gauge, and vacuum ranges. Model numbers reflect specific range configurations such as -005G for low-range gauge or -V100G for vacuum applications.

Economical calibration component
I purchased a DPG-108-100G gauge early 2022 to use for calibrating pressure switches that I use with controls in my hobby greenhouse. I had to partially slice the silicone boot to access the battery compartment door. This is not a problem as I only use this indoors for calibrations. 0.25% accuracy is sufficient for my applications. My only wish is that I could change the decimal point from xxx.x to xx.xx when using the PSIG scale.

Daily Use
We use these daily for checking pressure on a gas distribution system. For the price they are hard to beat. As long as you don't abuse it or let moisture and dirt into the transducer it holds up well.

Received; ready to integrate in our system
We have not yet used this but it looks pretty good.

Is there any risk of damage when applying vacuum (<0.1 bar abs) to a unit designed to read gauge pressure?
A small amount of vacuum in the range of -1 psi will not damage the unit, but higher vacuum pressure will affect the zero/span of the unit.
Date published: 2023-08-15
What is the resolution on the pressure readings?
Depending on the range the unit should have a resolution of 0.01 PSI
Date published: 2021-10-08
For gauge pressure models, is the accuracy +/- 0.25% of the reading or +/- 0.25% of full scale? The PDF manual implies the former, while the website write-up indicates the latter. Which is correct?
The accuracy rating of this gauge is % of full scale range.

Is it water-resistant?
Yes it is. Although it isn't shown in the photo the gauge comes standard with a silicone rubber boot. Rating is indicated in the specifications as IP68

I am looking for battery installation instructions for DPG108-100G unit that I purchased a few weeks ago.
There is battery cover secured by a small screw on the back of the unit. You can't see it because there is a very tight fitting silicone rubber boot covering case of gauge. You'll have to pull it off to get to the battery compartment. Battery is a standard 9V alkaline battery.

Do these gauges come with a NIST traceable calibration certificate?
Thank you for contacting Omega Engineering. Sorry but the DPG108 series gauges do not come standard with a calibration certificate. You can request it at time of order for an extra charge and lead time. Please contact our sales department for part number, price and lead time. Please feel free to contact us again if you have any additional questions.

How exactly do you remove silicone boot
Thank you for your inquiry, the Silicon boot\O-ring is a press fit, you should be able to pull it open.

Assume this gauge can be used with air along with liquids?
Duke, yes this unit can be used with air and liquids compatible with wetted Parts: 316 SS threads, NBR O-ring
