Quick Take
Choosing calibration equipment standards usually comes down to one question: what are you calibrating? This group spans a compact pressure calibrator, a higher-tier Fluke pressure model, a temperature calibrator/indicator sold for parts, and a full multi-product lab unit. The price gap between the least and most expensive is USD 22,401.50, and that gap is really a scope gap. Match the tool to your workload, not to the price tag.

|---|---|---|
| Pressure checks around -12 to 30 psi | Fluke 719 30G | It is a used pressure calibrator with that range on the label |
| Field pressure calibration with a Pro-level Fluke | Fluke 719Pro 300G | The Pro model is a used Fluke pressure calibrator at a higher price point |
| Temperature calibration on a very small budget | Thermo Electric 311600 Digi-Mite | It is the only temperature calibrator/indicator here, but it is for parts |
| Calibrating many electrical and temperature instruments | FLUKE 5500A | It covers voltage, current, resistance, frequency, and temperature simulation in one bench unit |
Product Notes
Fluke 719 30G Electric Pressure Calibrator 12 - 30 psi 719-30G
The Fluke 719 30G is the most direct choice if your pressure work stays within -12 to 30 psi. It is a used pressure calibrator priced at USD 1,200.00, and its specified range gives you both vacuum and low positive pressure coverage. That makes it a practical, focused option for routine pneumatic checks. The limitation is the same range: it will not help if you need higher pressures, and it does not handle temperature signals. You are also buying a used instrument, so your acceptance should depend on the physical condition of the unit when it arrives. For a shop that regularly works with 30 psi or lower, this is a clear fit.
Fluke 719Pro 300G Electric Pressure Calibrator 719Pro-300G 719 Pro
The Fluke 719Pro 300G is the Pro-level pressure calibrator at USD 2,999.99. If you want a used Fluke pressure calibrator with the Pro name and are willing to pay for that step up, this unit gives you that. It is in great working and cosmetic condition according to the seller, which is meaningful for a used instrument. The main limitation is in the package: this unit is sold as calibrator only, so the price covers the instrument itself, not a full kit. That distinction matters if you need a ready-to-go setup. Keep that in mind when you assemble your total spend.
Thermo Electric 311600 Temperature Calibrator Indicator Digi-Mite [A1B1
The Thermo Electric 311600 Digi-Mite is the low-priced outlier at USD 98.50, but the condition label tells the story: for parts or not working. It is the only temperature calibrator/indicator in the group, so if your focus is temperature rather than pressure, this is the option that points in that direction. The reason to consider it is cost and the possibility of repair; the limitation is that it cannot be treated as a working calibration instrument in its current state. The seller notes that it came from the parts crib of a closed plant, which explains its status. Budget for repair time and test equipment if you go this route.
FLUKE 5500A Machine Calibrator FLUKE 5500A FLUKE 5500A
The FLUKE 5500A is a different class of instrument. Priced at USD 22,500.00, it is a used multi-product calibrator for metrology laboratories. It integrates DC/AC voltage, DC/AC current, resistance, capacitance, frequency, thermocouple and RTD temperature simulation, and AC/DC power simulation. That makes it a strong candidate if your lab needs to calibrate digital multimeters, clamp meters, panel meters, data loggers, or process instruments. The limitation is the price and the fact that it is discontinued, so long-term parts and support may be less predictable. It is also a bench-top unit, not a handheld field tool, so plan for bench space and a lab-style workflow.
Final Recommendation by Use Case
For a working pressure calibrator in the -12 to 30 psi band, the Fluke 719 30G is the most practical match in this group. If you want a Pro-level Fluke pressure calibrator and are comfortable with a calibrator-only package, the 719Pro 300G is the one to evaluate. For temperature work on a tight budget, the Digi-Mite only makes sense if you are prepared to repair a for-parts unit. And if your lab needs broad electrical and temperature calibration coverage, the FLUKE 5500A is the only unit here with that level of scope.
