Pressure Flow Process Measurement: Calibrator or Gauge? Fluke 700G07, 718, 700G31, and TECHTONGDA

Choosing a pressure calibrator or digital pressure gauge for process measurement means balancing pressure range, portability, and whether you need a complete calibration setup or a single readout. The four options in this comparison cover listed prices from $450 to $1,200, and include Fluke's handheld calibrator, a 300 psi calibrator with fittings, a 10,000 PSI digital gauge, and a new hydraulic pump from TECHTONGDA. Each one has a different job. Understanding the difference between a calibrator and a gauge will help you choose the right tool for your process.

Quick Take

If you need a quick mental model: the Fluke 700G07 is a used pressure calibrator that sits near the low end of the price range. The Fluke 718 300G is the highest-priced option and adds a 300 Psi range plus case and fittings. The Fluke 700G31 is a 10,000 PSI digital gauge, not a calibrator. The TECHTONGDA is a new hydraulic pump for calibration work.

Product Notes

Fluke 700G07 Pressure Gauge Calibrator

This used Fluke calibrator is priced at $450.00, making it one of the lower-priced options here. It is titled Super Clean, and the screen still has plastic on it, with a like-new condition. If you want a Fluke pressure calibrator at the entry end of this price range, this is the one to consider. The tradeoff is that it is a used unit, so you are accepting a pre-owned condition rather than a new instrument. It is also a pressure calibrator rather than a gauge, so it is intended for calibration work instead of taking direct process readings.

Fluke 718 300G Pressure Calibrator

At $1,200.00, this is the most expensive option in the comparison. It is a used Fluke 718 with a 300 Psi pressure range, and it comes with a Fluke hard case and various fittings. The meter works perfectly and has no owner markings, with only slight signs of use. If you need a 300 psi calibrator with supportive accessories, this is the one to choose. The limitation is the price: it is more than twice the listed price of the lower-priced units, and it is still a used instrument rather than a new one.

Fluke 700G31 10K PSIG Digital Pressure Gauge

Priced at $549.00, this Fluke 700G31 is a digital pressure gauge rather than a calibrator. The title highlights a 10,000 PSI pressure range and IP67 rating, and the unit comes in a Fluke box. If you need a high-pressure readout for process measurement, this gives you that range without the cost of the 718. The limitation is that it is a gauge, not a calibrator, so you would need a separate pressure source or pump to perform calibration with it. It is a pre-owned unit in nice condition.

TECHTONGDA Industrial Pressure Calibrator Pump

This is the only new item in the group, priced at $450.26. The TECHTONGDA is a hydraulic pressure calibrator pump with a pressure range of 0-6Mpa and a vacuum range of -0.088-0. The structure is open and transparent, and it is designed for pressure gauge testing and calibration. For someone wanting a new pump rather than a used readout, this is the pick. The limitation is that the pump itself is not a pressure gauge or display, so you will need to pair it with a reference gauge or the device under test to complete a calibration setup.

Final Recommendation by Use Case

• If you want the lowest-priced Fluke calibrator and can accept used condition, choose the Fluke 700G07.
• If you need a 300 psi calibrator with case and fittings and are willing to pay more, choose the Fluke 718 300G.
• If you need a high-pressure digital gauge up to 10,000 PSI, choose the Fluke 700G31.
• If you want a new hydraulic pump for calibration work, choose the TECHTONGDA.
