When you work in pressure flow process measurement, the real decision isn't whether you need a calibrator-it's whether a dedicated unit like the Fluke 718 300G fits your workload and budget. This review looks at what a pre-owned example like this offers and who should consider it.
Quick verdict
The Fluke 718 300G is a straightforward choice if you specifically need to source and measure pressure up to 300 psi. At USD 1,200 for a used unit that reportedly works perfectly, you're getting a Fluke calibrator, a hard case, and various fittings that make it easier to connect to the process. If you only need occasional pressure checks and prefer a brand-new tool, this pre-owned route may not be for you.
Who it suits
This calibrator is for a technician or engineer who regularly verifies pressure in process lines and wants a single, portable unit for both sourcing and measuring pressure. If you work in instrumentation, HVAC, or plant maintenance and your pressures fall within 300 psi, this unit fits the workflow. It also suits someone who wants a hard case and fittings included in the price, so you don't need to buy accessories right away.
Fluke 718 300G Pressure Calibrator
The unit is described as working perfectly and showing no owner markings, which is a strong sign for a used tool. The reason to choose it is the complete package: a Fluke hard case and various fittings are included, so you can connect to common process fittings without buying extras. The limitation is the used condition-it shows slight signs of handling, so you need to be comfortable with a pre-owned tool.
Meaningful trade-offs
The biggest trade-off is the used condition. You're buying a pre-owned unit, so if you want a new tool instead, this used example isn't that. Also, because this is a dedicated pressure calibrator, it won't function as a multi-purpose process meter. If you need to measure temperature or other process variables, you're looking at a separate tool. And the pressure range is capped, so higher-pressure work requires a different model.
Bottom line
If you're specifically in the market for a pressure calibrator and you're comfortable with a used tool that shows slight wear, the Fluke 718 300G offers a practical, ready-to-use package at USD 1,200. It includes the essential case and fittings, and the reported functionality is exactly what you want from a calibrator. Just be honest about your pressure range and your appetite for pre-owned test equipment. If both line up, this is a solid purchase to put on the bench.
