When you are choosing a portable digital pressure instrument, the first decision is not the brand - it is how much pressure you need to read and what needs to come in the box. For pressure flow process measurement, you might be working on high-pressure lines or lower-pressure instrument circuits. Both of these instruments are used units, so the listed condition and what comes in the box matter as much as the specs. The Fluke 700G31 and the GE Druck DPI 705 sit on opposite sides of that split, and their prices sit at $549 and $180 respectively.
Quick verdict
If your checks routinely hit high pressure and you want an all-in-one used option, the Fluke 700G31 is the stronger instrument. If lower pressure coverage is enough and you are comfortable with a simpler purchase, the GE Druck DPI 705 offers a much lighter dent in the budget.

Where each product wins
The Fluke wins for high-pressure coverage and for buyers who value a ready-to-use set. The wide measurement span covers vacuum through high-pressure process checks, and the supplied box and accessories make it easy to protect and carry.
The Druck wins for lower-pressure work and for buyers who want less complexity. Its compact handheld format is easy to store, and the simpler setup keeps things straightforward.
Product notes
Fluke 700G31 10K PSIG Digital Pressure Gauge
The main reason to choose the Fluke 700G31 is its range. With a measurement span from -14 to 10,000 psi, this digital gauge can take on high-pressure hydraulic or process checks that the Druck cannot. The package includes the original Fluke box and accessories, so you are not hunting for a case or fittings. As a used unit, it is described as fully working and comes with a 30-day warranty, which gives the buyer a little breathing room. The trade-off is the price: at the higher end of this pairing, this gauge is worth it only when you actually need the extra range and the complete kit. If your work never approaches 10,000 psi, the added capability will not earn its keep.
GE Druck DPI 705 Handheld Digital Pressure Indicator
The Druck DPI 705 is a simpler way to add a portable pressure readout. It is a handheld indicator rated for 300 psig and comes with a black carry case, which is exactly what the seller shows: just those two items. The cost is well below the Fluke, which makes it an easy call when you only need low-pressure readings. What you give up is support and calibration confidence. The seller says it turns on and seems to work, but there is no recent calibration, no warranty, no returns, and all sales are final. This makes it a reasonable bet for non-critical setups or for someone comfortable performing their own verification checks. The 300 psig ceiling also means high-pressure work is off the table.
Final choice by use case
Choose the Fluke 700G31 when you need high-pressure verification and the convenience of a complete kit. Choose the GE Druck DPI 705 when your measurement work stays at lower pressures and you prefer a simpler, much lower-cost used instrument.
