Quick Take
Shopping for calibration equipment standards forces you to sort out very different formats under one name. In this group, a used Fluke pressure calibrator is offered as a working field unit, a Thermo Electric indicator is sold as parts or repair, a B&K null indicator powers on but is untested, and a Fluke TNT12000 listing is a repair service ticket rather than a device. The right choice depends on whether you need a ready-to-use calibrator, a restoration project, or a repair path for a unit you already own. The table below lays out how the four listings compare on listed price and basic condition.

| Fluke 719Pro 300G Electric Pressure Calibrator 719Pro-300G 719 Pro | You want a used pressure calibrator described as working in the field | It is the calibrator only, with the pictured items as the full package |

Product Notes
Fluke 719Pro 300G Electric Pressure Calibrator 719Pro-300G 719 Pro
This is the one pressure calibrator in the group that is described as being in great working and cosmetic condition. It was pulled from the field due to an upgrade, and the listed price is USD 2,999.99. The unit is a Fluke 719Pro 300G, so the brand and model are clearly identified. The practical catch is that this is the calibrator only, and the listing says it includes everything pictured only. Buyers should treat the photos as the scope of the package. If you need a current-style pressure calibrator and are comfortable with a used unit, this listing is the direct match.
Thermo Electric 311600 Temperature Calibrator Indicator Digi-Mite [A1B1
This unit is identified by MPN 311600 and has a Country of Origin listing of China. It is offered as a temperature calibrator indicator, but the listing states that it is being sold for parts or repair because testing was not performed. It came from the parts crib of a closed plant, which points toward a bench-project history. At USD 98.50, it is the second-lowest listed price in this group. The limitation is clear: do not expect a verified working temperature calibrator without troubleshooting. This is a reasonable choice for someone with the skills to diagnose and repair older electronic test equipment, not for someone looking for a ready-to-run calibrator.
B&K 750 Test Equipment Calibrator Null Indicator | POWERS ON UNTESTED
This vintage B&K unit is listed as a test equipment calibrator and null indicator. It is blue, wired, and used, and the listing says the light comes on when you plug it in, but no other tests have been performed. Scratches and imperfections are part of the package, and the item is sold as is. At USD 49.00, it is the lowest listed price in the group. The main limitation is the UNTESTED label. Power-on alone does not tell you whether the calibrator or null indicator functions correctly, so treat this as an as-is vintage project or a parts donor rather than a verification tool. Its age and cosmetic wear make it more suitable for someone who collects or repairs vintage test equipment.
FLUKE TNT12000 KIT Repair Service Ticket - Please Read
This listing is for a repair service ticket, not for a calibration instrument. It is aimed at Fluke TNT12000D, TNT12000WD, and TNT12000 Dosemate units and covers display replacement, battery replacement, power issues, and circuit board repairs. The listing is marked 'For parts or not working', which is consistent with a service-ticket format rather than a device listing. At USD 135.00, it is a targeted option for someone who already owns one of those TNT12000-family units and wants professional repair coverage. The limitation is that it will not give you a second calibrator or a spare unit; it is a path to restoring an existing TNT12000 instrument to reliable operation.
Final Recommendations by Use Case
- If you need a field-ready pressure calibrator, the Fluke 719Pro 300G is the only listing in this group described as being in working condition. Choose it when the goal is a usable calibrator rather than a repair project.
- If you already own a TNT12000D, TNT12000WD, or TNT12000, the FLUKE TNT12000 KIT Repair Service Ticket is the only option here that addresses display, battery, power, and board repair for that family.
- If you enjoy troubleshooting older electronics, the Thermo Electric 311600 Digi-Mite gives you a temperature calibrator indicator with known parts-or-repair status and an unverified function.
- If you want a vintage test-equipment piece with the lowest listed price in the group, the B&K 750 null indicator powers on, is untested, and is sold as-is.
