Choosing between the Fluke 719 30G pressure calibrator and the Thermo Electric Digi-Mite temperature calibrator is really a choice between a ready-to-use pressure tool and a low-cost repair project. The Fluke covers -12 to 30 psi and is listed as Used; the Thermo Electric is for parts or not working. Your decision comes down to whether you need a working calibrator or want to take on a fixable unit.
Quick Verdict
Choose the Fluke 719 30G if your work centers on pressure calibration and you want a unit with a specified range, even though it is used. Choose the Thermo Electric Digi-Mite only if you are buying a temperature calibrator as a repair project and you have the skills to diagnose and fix it. The Fluke is the practical purchase; the Digi-Mite is the speculative one.
Side-by-Side Comparison
| Product | Price | Calibration focus | Condition |
|---|---|---|---|
| Fluke 719 30G Electric Pressure Calibrator | USD 1,200.00 | Pressure, -12 to 30 psi | Used |
| Thermo Electric 311600 Temperature Calibrator Indicator Digi-Mite | USD 98.50 | Temperature calibration/indication | For parts or not working |
Where Each Product Wins
The Fluke 719 30G wins for anyone who needs pressure calibration in the -12 to 30 psi range. It also wins on clarity: you know exactly what measurement range it covers. The Thermo Electric Digi-Mite wins only on price and on temperature-calibration focus. Because it is sold for parts or not working, the Digi-Mite is not a direct competitor for someone who needs a working calibrator immediately.
Product Notes
#### Fluke 719 30G Electric Pressure Calibrator
This used pressure calibrator covers -12 to 30 psi, which makes it a direct match for pressure calibration work in that range. The MPN is 719 30G, and the unit is listed in Used condition. The concrete reason to choose it is the range: you get a pressure-specific tool with a clear specification. The limitation is the condition, Used rather than new, so this is not a fresh-from-the-box instrument. If your process demands pressure calibration and you are comfortable buying used equipment, this unit has the right focus.
#### Thermo Electric 311600 Temperature Calibrator Indicator Digi-Mite
The draw here is the price: USD 98.50 is a low entry point for a temperature calibrator/indicator from Thermo Electric / Digi-Mite. However, the condition is for parts or not working, which means there is no assurance that the unit will perform. The MPN 311600 and country of origin China are listed, but the practical reality is that you are buying a repair project. If you have the diagnostic skills to test and fix it, the Digi-Mite could be a useful temperature indicator. If not, the low price still buys a questionable unit.
Final Choice by Use Case
If you need a pressure calibrator, choose the Fluke 719 30G. If you need a low-cost temperature calibrator/indicator and can repair it yourself, the Thermo Electric Digi-Mite is the budget option. If you need a working calibrator without repair work, the Fluke is the better bet. Match the calibration focus to your workload, and let condition decide how much hands-on work you are willing to do.
