When you're setting up a pressure flow process measurement toolkit, the choice between these two Fluke instruments comes down to one question: do you need to calibrate pressure sensors, or do you need to measure high-pressure systems directly? The Fluke 700G07 Pressure Gauge Calibrator and the Fluke 700G31 10K PSIG Digital Pressure Gauge are both used Fluke tools with clear strengths, but they solve different problems.
Quick Verdict
If your main task is verifying and adjusting pressure instruments, the 700G07 is the more direct fit. If you need to read pressures up to 10,000 PSI in a rugged field environment, the 700G31 is the obvious pick.
At a Glance

Where Each Product Wins
The Fluke 700G07 wins for calibration work. It's built as a pressure calibrator, and this specific unit is in super-clean condition with the protective plastic still on the screen. At $450, it's the lower-priced option. The Fluke 700G31 wins for high-pressure measurement. Its -14 to 10,000 PSI range covers a wide span, and the IP67 rating helps it resist dust and water. It also comes in the original Fluke box with accessories and includes a 30-day warranty.
Product Notes
Fluke 700G07 Pressure Gauge Calibrator
Calibration jobs are where the 700G07 earns its keep. As a dedicated pressure calibrator, it's designed to compare and adjust readings on pressure-based instruments. This used unit is in super-clean condition, with the screen still protected by plastic, which suggests careful handling. Its price of $450 makes it the less expensive of the two Fluke units, leaving room in the budget for other gear. The trade-off: this is a calibrator, not a high-range measuring gauge. If your work routinely involves pressures near 10,000 PSI, you'll need to reach for something like the 700G31 instead. For routine calibration within common pressure ranges, the 700G07 is a solid choice.
Fluke 700G31 10K PSIG Digital Pressure Gauge
The 700G31 is the heavy hitter for high-pressure field work. With a pressure range of -14 to 10,000 PSI, it handles hydraulic and pneumatic systems that exceed the reach of typical gauges. The IP67 rating adds confidence when dust or water is part of the job environment. It arrives in the original Fluke box with its accessories, and a 30-day warranty backs the purchase. At $549, it costs $99 more than the 700G07, but that higher price buys a much wider measurement span. The limitation is that it's a gauge, not a calibrator-you can't use it to generate or fine-tune pressure, so you'll still want a calibrator like the 700G07 for that function.
Final Choice by Use Case
Choose the Fluke 700G07 if you're a technician who primarily calibrates pressure instruments and you want a clean, lower-cost Fluke calibrator. Choose the Fluke 700G31 if you work with high-pressure systems up to 10,000 PSI and need a rugged digital gauge with IP67 protection.
